Determination of Sodium (Na) Content in Table Salt by Atomic Absorption Spectrometer (AAS)
Вставка
- Опубліковано 18 сер 2020
- Determination of Sodium in table salt is an important testing parameter. Sodium is a mineral that occurs naturally in foods or is added during manufacturing. Because excessive amount of sodium in any food is poisonous. This video represents the complete procedure of Sodium analysis by using AAS. ______________________________________________________________________

You describe amazingly
Thank you
Thanks for sharing 🙏
My pleasure
hello, thank you for this work
please can you send me the procedure (step 1 and step 2) in pdf file
Sorry we dont have pdf of any method.
Hi why multiplying by 10000 to get the percentage
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 :)
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.
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?
You have to put Dilution Factor of the sample preparation into the software to get the final results based on calibration curve
Sir, how can I know about chemicals required for standard preparation for various heavy metals..
You can hire a consultant for help. Write us at mail.mic.chem@gmail.com
Please more videos on AAS :)
Please mention the test parameter

AU please😃
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
You are right. 64.2 ml is needed. But slight variation in the nitriv acid concentration will not affect your teat result.
Nice
Thanks
Thnks, but I think it is better to input dilution factor during analysis rather than calculating manually
Ok. Noted
Hi,Can you please tell me what are the important parameters we can check by using spectrophotometer in food industry.
Take help from Google
@@MicroChemsExperiments Ok
Hi 👋🏻 can you explain why is it 100/4,7 and 100/1 please? Thanks a lot and great video ❤️
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.
I didn't find 100/4 and 7. Please specify with video time. Thank you.

@@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 you explain me where did that 10000 came from in the formula
To covert the ppm value to percentage you need to divide the ppm value by 10,000.
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
Your prepared concentrations are much higher for AAS analysis. Prepare 1ppm, 3ppm & 6ppm
Can I use HCl instead of HNO3?
No.
please for GFAAS video
Noted.
Kindly upload the procedure for creating method for AAS thermoscientific 3000 series
What do you mean by creating method? Please clarify.
Thank you.
I mean creating a method file on AAS software for analyzing sodium
@@gracefulheart7910 Ok. I will make the video soon. Stay with us.
@@MicroChemsExperiments Thankz a lot !
@@gracefulheart7910 Most welcome
Hello, are you using the sodium hollow cathode lamp or it should be turned off
Yes. Sodium hollow cathod lamp
@@MicroChemsExperiments yes what? turned off or turned on

How Glass volumetric flasks used this analysis
Your question is not clear. Please rephrase it
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
@@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.
