What is the easiest way to test for lead in soil? i need to know PPM for a school project? - ppm or prospectus
Is it necessary to use a gas chromatograph to? expensive? Their solutions are?
I do a study on lead in soil in the vicinity of industrial sites and would require a detailed examination of ppm lead to.
Please leave sources or information, contact the laboratory if necessary.
Thank you.

Ppm Or Prospectus What Is The Easiest Way To Test For Lead In Soil? I Need To Know PPM For A School Project?

I think you need and energy dispersive X ray fluorescence spectrometer. Tip: Visit the website of the INNOV-X (XRF-brand) or JEOL (www.jeol.com) RFA-mark.
Gas chromatography is based on the silence of lead.
All atomic absorption, graphite furnace AA calls or inductively coupled plasma-mass spectrometry, it would be the best choice, but from the expensive (several thousand) AA for tens of thousands of GF-AA hundreds ICP - MS.
I would say that a certain type of gravimetric analysis, the best choice for not much money.
I have no law on the hand, but it would probably be the first to carry the soil sample treated with nitric acid and other metal ions to dissolve. You can then filter and treat substance is filtered with hydrochloric acid to the silver, mercury and lead precipitation.
You can then use this filter OUT and hot water (), almost boiling water to dissolve the chloride. Cool on the, and should also be left with nothing but a precipitate of lead chloride. Filter on filter paper without ashes then burn it in a crucible.
If you know your soil mass origin, and mLead chloride ass collected, should be fairly easy to determine the parts per million of lead.
Good luck!
