Polymers for the Extraction of Chromium—Role of Polymers in the Removal and Recovery of Chromium from Wastewater

Abstract

The present review discusses different possible routes of removal and recovery of chromium from industry and laboratory wastewater with special emphasis on the role of polymers in this context. Polymers can play a vital role in the easy, rapid and cost effective separation of chromium from aqueous solutions. Such studies of separation are important from the standpoint of identifying selective hosts and extractors for chromium. The use of suitable polymers in the removal and recovery of chromium from solutions is discussed.
