The Removal of Soluble Mercury from Waste Water by Complexing Techniques,

摘要

Milk proteins,xanthates,modified rubber products,and keratin in various forms can be used for the removal of ionic mercury from water systems. In particular anionic and cationic ion exchange products made from ground tire cord rubber compete very favorably with classical ion exchange resins with regard to capacity,and rate of pick-up. Cow and pig hair selectively remove ionic mercury and the performance with tannery hair based on equilibrium capacity,rate of removal and pressure drop was good. Regenerative studies of ionic mercury from tannery hair with HCl and NaCl were successful,and a number of scale-up studies including economics were completed to illustrate how tannery hair might be used for the treatment of waste streams containing ionic mercury.
