ĐÁNH GIÁ HIỆU QUẢ XỬ LÝ MỘT SỐ ION KIM LOẠI NẶNG TRONG NƯỚC CỦA 2,3-DIMERCAPTOSUCCINIC ACID (DMSA)

Tóm tắt

The environment and its compartments have been severely polluted by heavy metals. Heavy metals
toxicity can result in damaging or reducing mental and central nervous function, lowering energy
levels, and damaging to blood composition, lungs, kidneys, liver and other vital organs. 2,3-
dimercaptosuccinic acid (DMSA) is a sulfhydryl-containing, water-soluble, non-toxic, orallyadministered metal chelator which has been used as an antidote to heavy metal toxicity since the 1950s.
This paper presents the results of the removal efficiency evaluation for heavy metal ions, including
Pb(II), Hg(II), Cd(II) and As(V). The maximum removal efficiency of Pb(II) (at pH 7), Hg (II), Cd(II)
(at pH 2.5) and As(V) (at pH 5) were of 99.98%, 99.87%, 82.40% and 83.39%, respectively.
