Abstract:

A study was carried out to determine the different concentration of potassium thiosulfate inside of the solid which affect the exchange condition content of Cu2+,Zn2+, Mn2+，Al3+. A pot experiment studied the effect of different concentration K2S2O3 on the content of heavy metals in maize.The result indicated that the consistency of Cu2+,Zn2+,Mn2+ 's increase along with the potassium thiosulfate which inputs to increase, the consistency of Al3+'s increase along with the potassium thiosulfate which inputs to reduce. The high content of K2S2O3 contains certain toxicity itself,which can inhibit the growth of plant and reduce the biomass greatly
