SORPTION PURIFICATION OF EFFLUENT WATER FROM HEAVY METAL IONS BY MODIFIED NATURAL ZEOLITES
Abstract and keywords
Abstract (English):
Features of sorption method of effluent water purification are considered. Analysis of technologies of effluent water purification from heavy metalsionsis presented. Physico-chemical regularities of sorption of Zn, Ni, Cu ions are investigated. As sorbents it is proposed to use zeolites of Holinsky deposits, modified by sulfur polymer, obtained from waste of epichlorohydrin production. This will allow simultaneously solving two problems: elimination of waste and wastewater purification, which is significantly advantageous from the economic point of view. Kinetic curves of sorption of Zn, Ni, Cu ions in different solution concentrations are presented. Also the adsorption process of heavy metal ions from solutions of chemically modified zeolites in the evaluation of the influence of various factors (the contact time of sorbent with solution, pH and temperature) are investigated.

Keywords:
sorption, waste water, zeolite, ions of heavy metals, treayment.
