i mean without Atomic Absorption ..

Hi Asim,

ICP-OES (or ICP-MS) spectroscopy is very effective to determine metal concentrations in water. If this is not available you can look into simple spectrophotometrical methods. For instance, you can make the ortho-fenantroline method to detect iron. There will certainly exist a spectrophotometrical method to measure arsenic. You can dig into the literature in order to find an appropriate one.

Good luck!

Niels

Dear Sir, Vis-spectrophotometer can be used for iron and arsenic detection. Likewise this iron can also be detected by Palin test kit which uses a color comparator and also supportive reagents

Thank you to both of you.Actually, i want to check this without any instrument. I know about Spectrophotometer & other instruments and palin test kits, hanna test kits etc

simply using chemicals in lab

like Niels Wardenier has mentioned

ortho-phenanthroline method

Actually, the ortho-phenantroline method requires a spectrophotometer to determine the concentration of iron in your sample. If you simply add the chemicals to the samples and an orange-red color develops, you can be quite sure that iron is present.

ok..
