In this chapter, the feasibility of kaolinite like alternative adsorbent for
wastewater treatment has been discussed. Kaolinite is widely used in various industrial
processes. Besides these applications, kaolinite has also been used in the environmental
applications, with special emphasis on the treatment of industrial effluents. Due to its
low cost and efficient adsorptive character, its utilization has been studied for the
removal of flotation reagents in iron mineral processing and dyes from wastewater in
textile industry. A detailed characterization of kaolinite is presented. The results
demonstrated that kaolinite has higher potential for these organic compounds which
makes it a good alternative for the wastewater treatment. The adsorption kinetics and
isotherms have also been discussed.
