Abstract

Abstract It is known from experience that mercury leaks from chelate resin columns which are used for mercury wastewater treatment. In this paper, one of the reasons for the mercury leakage phenomena is discussed. After shaking the synthetic mercury wastewater with chelate resin, the supernatant became turbid. Using a highly sensitive mercury analysis, it was found that the results at lower mercury concentrations deviated from the Freundlich relation. From the results, it was presumed that the chelate component was detached by friction in the process of packing chelate resin into the column, and this chelate component adsorbed mercury while passing through the column.
