CATIONIC EXCHANGER FROM POLYMERISED BIO-MATERIAL WASTES - A DEVICE FOR CONCENTRATING AND RECOVERING METAL IONS FROM EFFUENTS. By: OGBAN, I. U. & UNO, U. A.

ABSTRACT

Cationic exchanger was produced by co-polmerization of furfuraldehyde (palm nut fibre/corn -cob) and tannin (onion skin/peanut) under acid and base catalysis. Exchange process, distillation and membrane filtration were employed sequentially to optimally eliminate organic, inorganic and particulate matter present in waste water. Characterization  of  the  exchanger  revealed  that  the  degree  of  polymerization  was  a  function  of  high  exchange  site  and  hence  efficiency.  The Sorptive  capacity  of  the  characterized resins  (1.85meq/g),  measured  favourably  with  the  commercial  Wofatit  P.(1.9meq/g). The state of the art and the development of the catalytic technology in the area of water treatment are economical and offer opportunities for waste material utilization.
