what type of targeted compounds in water did you plan for determination. Your statement incomplete and difficult for us to give suggestion

Huda M.H

thanks for your interest I want to take samples of tap water to investigate the presence of contamination like heavy metals Cd,Cu,Fe,Mn or mercury or sulfate or phosphorus ingridients

Fouad Fadhil Al-Qaim

I suggest to use Atomic Absorption instrument, so you should select the proper HCL for each metal. Some times, you can use ICP-MS but I think this instrument not vailable in IRAQ. Tq

Heavy metals - you can analysis by using atomic absorption spectroscopy (aas), inductively couple plasma - optical emission spectroscopy (icp-oes) or mass spectrometry (icp-ms) which more sensitive and precise.

For sulphate and phosphorus - it most suitable determine using ion chromatography (IC). Alternatively you can analysis using Acid Persulfate Digestion Method (Total Phosphorus), Ascorbic Acid method (orthophosphate/ reactive phosphorus).

thanks very much for everyone for your interest and help I really appreciate your assistance
