Phreeqc training video 1

[@jsaezf1757]

Great video! have done PHREEQC in my geochem MSc,but this is a fantastic refreshing! congrats!!

[@wtamubsinenvironmentalengi9672]

Great video! It is really good because you don't assume that people don't know too much already about all of the water chemistry. You give enough basics in here that people know what is happening but don't spend so much time on any basics that people that already know a lot would get bored. This seems really helpful and just makes PHREEQC seem more accessible in general. Thanks!

[@stephenmuma-o4p]

This is a great video. when are you going to release another video PHREEQC 2 video Please?

[@lelainateichert1094]

Thanks, good explanaition. :) Another one about what else to do in PhreeqC would be nice :)

[@yerdauletabuov7922]

Great explanation, man! I have just started learning this software and you gave me a good understanding for now.

[@snowelfracinghorsemanship]

Thank you for an informative video, well done on explaining!

[@arden9332]

Thanks for the great tutorial! It had really helped me get started using PHREEQC

[@amirhaidari1105]

Hi Jezdez, Great work and very useful. Please continue with the tutorial?

[@stelisk1]

Hello sir, are you planning to give us a second training video for Phreeqc ? The first one was very very useful !!

[@lancelotpetit4030]

Please video 2 ! It was very helpfull, i'm studying applied bio geochemistry and this software is part of the skills needed to pass the exam !

[@mojtabazaresefat296]

Very helpful indeed. Many thanks, I am waiting for next training video....

[@narendra848]

Great work..... this will help many phreeqc user to learn the software........ can u make one on working as there is no discussion on the working of phreeqc on the forum

[@erciyuan-o1b]

Thank you very much,it's useful for me

[@robertaaraujo477]

good night, do you have any tips about how to find indium especiation database?

[@aa23-y6]

Sir, How did you add Uranium in the list ? I need to do uranium speciation, for that firstly i have to add uranium in the input list

[@rasmus619]

PfW is an embedded version of the alternative GUI Phreeqc for Windows developed by Vincent van Post

[@trinh123456]

Hi mate, Not sure if you could send me the library files as promised :) maybe you are busy recently I guess… but please send and I will see if my list is extended. Thanks!

[@rajkamalmohan5924]

Good explanation. Waiting for PHREEQC Video 2 with some examples of water vs equilibrium phase (like calcite)

[@TailorBO]

Very helpful indeed. Thank you for this tutorial.

[@jezdez1]

Your welcome.

[@lanangdelonixregia4525]

Thank you, very useful video. I have a question. In principle, I did the same thing but added reactants (batch reaction) and the results that appeared in the species distribution were moles V cm/moles which had a negative number. is this a numerical error or is there another meaning to this negative value? Thank You

[@robertaaraujo477]

is there any experimental way to find alkalinity?

[@gvallot5549]

Thank you, very pedagogical video. I would like to have one which explain how to install this software because I can't manage to do it.

[@Jack-hf1pe]

Under USGS, find the site with PHREEQC version 3. The version that he is using is phreeqci-3.7.0-15749.msi [13M] under graphical user interfaces.

[@MarianaGarcia-ev9rt]

Hi, could you please tell me where can I find a tutorial to do ph - diagrams with phreeqc?

[@Mfrelogui]

Hi, thanks for the tutorial but i have a question, where can i get the database of the solution master species?

[@jezdez1]

Hi. There are databases that come with PHREEQC. You can add to them which is what i do. There may be more recent solubility / speciation constants so you can add these or change them.

[@Mfrelogui]

@@jezdez1 please, could you tell me where can i find the solubility/speciation constants? and thank you very much for your help

[@jezdez1]

@@Mfrelogui I get mine from published papers. What system are you interested in?

[@Mfrelogui]

@@jezdez1 aahh ok, well i'm interested in performing the chemical speciation of some trace metals in phreeqc

[@stephenmuma-o4p]

@@Mfrelogui did you find more database? I am having trouble on where to find them and if you have kindly share the link for the same database so can download. Thank you

[@mango5660]

Clear explanation, thank you :)

Lovely video please can some one help with the configuration of this software on MacBook pro..I'm experiencing difficulty configuring on my MacBook pro

[@fatimaafsari]

Hello, do you have a Phreeqc training in private?

[@robertaaraujo477]

how can i look at that database?

[@AJITKUMAR-th8tt]

please sir one tutorial surface complexation are upload

[@robertaaraujo477]

sorry, how do you modify the phreeqc database?

[@smitakshimedhi6652]

Sir I have downloaded the software but it doesn't contain 'As'.Sir is there any way to add that? Kindly please say.

[@trinh123456]

Hi Jezdez1, thanks much for the video. There are two things I would like to ask: 1) how to get the Minteq database file and where to replace the original version with your modified version? 2) How come your PHREEQC interactive version has so many elements/species in the Individual element input, because my version only has limited elements or species? is your a paid version? Thanks. I hope to get your reply :)

[@jezdez1]

Hi. Thanks for your message. The Phreeqc software is free. I sometimes add data to it especially if new constants appear in a paper or database. The data base I use is based on minteq

[@trinh123456]

Hi Jezdez :) Thanks so much for your reply. I thought my question is never answered since I do not see you active recently. Do you mean after adding new constant, the program will enable the selection of the new added species? For example, if K+ is greyed out, it will be “selectable/clickable” in the PHREEQC windows after you add the relevant equation and constant that relates to K+? Please show where the path to the minteq database in the computer. Thanks Jezdez!

[@jezdez1]

@@trinh123456 not quite sure what you mean. Can you explain a different way. I'll look at your reply tomorrow as it's nearly midnight in the UK

[@trinh123456]

Hi Jezdez, Sure no problem. What I meant is in the “individual element input” tab in the “Solution” window that Pops up after double click on the “Solution 1”, there is a very limited number of available cations and anions for me to select, and most of them are greyed out. I dont know why your list is much more than my list :) Thanks and have a good night, Jezdez!

Hello! First of all i want to thank you for this tutorial. Could you please show me how to calculate a hydrothermal fluid with up to 300°C that comes in contact with a solid rock? the composition of that rock is basaltic. Thank you
