Determination of Sodium (Na) Content in Table Salt by Atomic Absorption Spectrometer (AAS)

[@Nony709]

I’m from 🇸🇦 my doctor today made the class watch your video, it’s really good and helpful thank you 💗

[@MicroChemsExperiments]

Thanks for sharing. I feel so proud and it means a lot for me.

[@xfh35m]

You saved my life, Thanks so much for the video. but if i may ask, how do you come about the "sodium standard of 1000 PPM" in which from which was used to prepare each of the sodium standards? Thanks

[@madmenvlogs4271]

You describe amazingly

[@MicroChemsExperiments]

Thank you

[@Offecon]

Please, would you explain why you did not add the nitric acid to the samples and why you didn't add cesium?

[@mohammedadjeli6849]

hello, thank you for this work please can you send me the procedure (step 1 and step 2) in pdf file

[@MicroChemsExperiments]

Sorry we dont have pdf of any method.

[@gracefulheart7910]

Kindly upload the procedure for creating method for AAS thermoscientific 3000 series

[@MicroChemsExperiments]

What do you mean by creating method? Please clarify. Thank you.

[@gracefulheart7910]

I mean creating a method file on AAS software for analyzing sodium

[@MicroChemsExperiments]

@@gracefulheart7910 Ok. I will make the video soon. Stay with us.

Sir, how can I know about chemicals required for standard preparation for various heavy metals..

[@MicroChemsExperiments]

You can hire a consultant for help. Write us at [e-mail]

[@Naveenbabuborugadda]

Where is standard preparation link?

[@nuramalia5486]

please help me!! can we actually get the actual concentration straight away from the generated data from AAS? or we still need to find the concentration from the calibration curve of the standard? basically by using the formula y = mx + c?

[@MicroChemsExperiments]

You have to put Dilution Factor of the sample preparation into the software to get the final results based on calibration curve

Sir Iron(fe) ke liye kitna sample lena pdega plzz tell.

[@MicroChemsExperiments]

Take 2g of sample and dilute to volume 100ml for Iron analysis

[@madmenvlogs4271]

Hi can you please tell me how you used 69.75ml hno3 used for 1N solution ... In my piont of view it should be 64.2ml

[@MicroChemsExperiments]

You are right. 64.2 ml is needed. But slight variation in the nitriv acid concentration will not affect your teat result.

Hi,Can you please tell me what are the important parameters we can check by using spectrophotometer in food industry.

[@aydanyldz5915]

hello, why are we doing the watching process? Why did we dilute a second time and measure both? Finally, how do we calculate ppm concentrations? thank you for the video :)

[@MicroChemsExperiments]

Ppm calculation and percentage calculation are already given in this video. As the sample have the unknown concentration of Sodium, we diluted second time and measure both to ensure that any of the dilution absorbances falls within the standard curve.

Hello, are you using the sodium hollow cathode lamp or it should be turned off

[@MicroChemsExperiments]

Yes. Sodium hollow cathod lamp

[@shanmugamshan1982]

Can you explain me where did that 10000 came from in the formula

[@MicroChemsExperiments]

To covert the ppm value to percentage you need to divide the ppm value by 10,000.

[@ChriehChigaba]

Hi why multiplying by 10000 to get the percentage

Thnks, but I think it is better to input dilution factor during analysis rather than calculating manually

[@annieheart9475]

Hi 👋🏻 can you explain why is it 100/4,7 and 100/1 please? Thanks a lot and great video ❤️

[@MicroChemsExperiments]

During the sample preparation, we diluted 1 ml of our first sample solution into 100ml with DI in order to make 2nd dilution. Thats why, 100/1 is used in the calculation.

[@MicroChemsExperiments]

I didn't find 100/4 and 7. Please specify with video time. Thank you.

[@annieheart9475]

@@MicroChemsExperiments 4:31

[@MicroChemsExperiments]

@@annieheart9475 Oppss....Sorry. We did a silly mistake. 100/0.006 should be written in place of 100/4.7. Because we dissolved 0.006g (6mg) sample into 100ml DI water.

Can I use HCl instead of HNO3?

No.

[@vaheatoyan6875]

Thanks for video, can u please explain me what am I doing wrong. I prepared 50ppm ZnSO4 7H2O solution and dilute it twice for second an 5 times for 3rd standard. For 50ppm I got 0.260 absorbance but for 25ppm I got 0.220 absorbance which could not be correct. I did this few times and get same results, can you give me advice how I can fix it

[@MicroChemsExperiments]

Your prepared concentrations are much higher for AAS analysis. Prepare 1ppm, 3ppm & 6ppm

[@rameshkumar-ge5xl]

How Glass volumetric flasks used this analysis

[@MicroChemsExperiments]

Your question is not clear. Please rephrase it

[@rameshkumar-ge5xl]

Glass flasks made-up of metals so so teflon flasks or Tarsons used for metal contents but you are used Glass flasks how you described this

[@MicroChemsExperiments]

@@rameshkumar-ge5xl Metals doesn't leach from the glass flask. You can use this with no confusion. Using glass utensils is completely safe for heavy metals and minerals analysis.
