Study of Cadmium Wastewater Treatment with Polymer PHA Containing Hydroxamic Acid Groups

Abstract:

Polymer heavy metal chelating agent containing hydroxamic acid groups (PHA) was made in order to observe its effects on the removal rate of Cd²⁺. The present study reaches the following results: (1) On conditions that pH value is 8.0, the chelating agent is 60mg•L^-1 and the reaction time is 60min, the highest chelating capacity of the polymer heavy metal chelating agent PHA can reach 341 mg/g. (2) The existence of common cations: K⁺, Na⁺and Mg²⁺ can improve PHA’s ability to remove Cd²⁺. (3) The existence of common anions Cl^-, SO₄^2- and NO₃^- can improve PHA’s ability to remove Cd²⁺. (4) Co-existing with the turbidity-causing materials, PHA’s removal abilities of Cd²⁺ and turbidity are mutually promotive. (5) The chelating product, Cd-PHA’s amount of leaching of Cd²⁺ is only 1/11 of that in neutralization titration ,having a relatively higher stability and better environmental safety.
