Abstract

 THE PRESENT STUDY EXPLAIN THE EFFECT OF PH, METAL ION CONCENTRATION, AND CONTACT TIME ON THE ADSORPTION OF CR (III) IONSFROM AQUEOUS SOLUTIONS BYTYPHA LATIFOLIA L. ROOT, AS A BIOMASS. FOR THIS PURPOSE, THE ROOT SECTION OFTYPHA LATIFOLIA L. BIOMASS WAS PRETREATED CHEMICALLY WITH SODIUM HYDROXIDE. THE MAXIMUM ADSORPTION CAPACITY WAS OBSERVED AT PH 5, WHEN THE INITIAL CONCENTRATION OF METAL ION WAS 100 MG/L. IT WAS FOUND THAT THE ADSORPTION PROCESS WAS REACHED EQUILIBRIUM DURING 60 MIN CONTACT TIME WITH FIXED BIOMASS DOSE OF 1 G/L. THE KINETIC STUDIES SHOWED THAT THE ADSORPTION RATE CONSTANTS COULD BE CALCULATED BETTER BYPSEUDOSECOND ORDER EXPRESSION WHICH MORE COMMONLY APPLIED AS A LAGERGREN EQUATION. THE ADSORPTION DATA COULD BE FITTED WELL TO LANGMUIR AND FREUNDLICH ADSORPTION ISOTHERM WITH COEFFICIENT OFDETERMINATION VALUES GREATER THAN 0.96. THE VALUES OF SEPARATION PARAMETER WERE IN THE RANGE OF 0–1WHICH THIS INDICATED THAT THE ADSORPTION PROCESS IS FAVORABLE [1, 2]. IT HAS BEEN SUGGESTED THAT PRETREATEDTYPHA LATIFOLIA L. ROOT CAN BE SUCCESSFULLY APPLIED FOR THE REMOVAL OF TOXIC HEAVY METAL IONS SUCH AS CR (III) FROM AQUEOUS SOLUTIONS [3].
