Phenol and Formaldehyde Cationic Resin Blended with Sulphonated Aegle Marmelos Charcoal

Abstract

This paper represents a simple method for preparing and characterizing of low-cost ion exchangers of sulfonated carbon prepared from Aegle Marmelos., as a source of cheap plant material blended with phenol-formaldehyde as a cross linking agent. The prepared ion exchange resins (IERS) are characterized by infrared (IR) spectral and thermal studies. All the important physico chemical properties of the ion exchangers have been determined. It is concluded from the present study that PER sample could be blended with 30% (W/W) of sulfonated Aegle Marmelos charcoal (SAMC) without affecting its physico chemical, spectral and thermal properties. Hence blending with SAMC will be finitely lower the cost of the ion exchange resin. Ion exchange process is suitable in the treatment of waste water containing metal ions discharge from plating and other industries. Also, it is a convenient way to concentrate and remove the ions of valuable metals like copper, mercury, cadmium, Nickel and Barium special processes using selective IERS are also available for the recovery of precisious noble metals like gold, platinum and silver. The present study is aimed at to synthesize and characterize new composite ion exchangers of PhOH – HCHO type, blended with SAMC and to determine the column/cation exchange capacity (or) ion exchange capacity (IEC) for some selective metal ions.
