[Application of ICP-MS to detecting ten kinds of heavy metals in KCl fertilizer].
With the rapid development of society, more and more attention has been focused on environmental safety, especially on the pollutions of heavy metals, pesticides, persistent organic pollutants and deleterious microorganism. Heavy metals are difficult to metabolize in human body are quite harmful, so research on the pollution of heavy metals is increasingly important. There are many pollution sources of heavy metals, including waste residue, waste water and exhaust gas from industry and automobile, and garbage from human life. The contents of 10 kinds of heavy metals (Cr, Ni, Cu, As, Cd, Sn, Sb, Hg, Tl and Pb) in potassium fertilizer (KCl) from Russia were analyzed by ICP-MS. The results showed that potassium fertilizer (KCl) contained less heavy metals than organic-inorganic compound fertilizer; the content of heavy metals Cr, Ni, Cu, As, Cd, Sn, Sb, Hg, Tl and Pb is 0.00, 65.54, 238.85, 190.60, 0.98, 14.98, 2.97, 10.04, 1.28 and 97.42 ng x g(-1), respectively, which accords with the correlative standards. All the data showed that if potassium fertilizer (KCl) is manufactured through normal channel, the content of heavy metals should be little and safe.
