Application of Guar Gum based Polymers in Drug Removal from Waste Water

Abstract: Biodegradable polymers have unique properties hence finduse in different fields like medicinal, agricultural, industrial, environmental field etc. They lead to zero waste therefore known as speciality materials. Biopolymer guar gum can be extracted from the seeds of the plant Cyamopsistetragonolobus. It is a biopolymer consisting of β, 1-4-linked linear mannose chain interposed with α, 1-6-linked galactose units. Guargum consist of no. of hydroxyl functionalities which give of hydrogel character by the interaction with water molecules through hydrogen bonding. Guar gum is used in various industries for the removal of hazardous dyes. The dye removal studies were performed with respect to contact time, temperature, pH and dye feed concentration removal. This review will help the future researchers who are working on the environmental solutions based on biopolymers.
