SINTESIS KARBON MESOPORI, CMK-1 DAN POTENSI ADSORPSINYA ATAS SURFAKTAN DI PERAIRAN

Abstract

Marina Chimica Acta 5(1) 2004Adsorption of sodium dodecyl benzene sulfonate (SDBS) on mesoporous carbon, CMK-1 with a variation\ud of the contact time, the concentration of SDBS and a variation of pH has been conducted. The\ud concentration of SDBS before and after adsorption was determined by a UV spectrophotometer. Freundlich\ud and Langmuir models were used to study the adsorption capacity of SDBS by CMK-1. The Results\ud showed that the optimum contact time was 4 hours. To know the adsorption capacity of SDBS on CMK-1,\ud adsorption of SDBS at various consentrations and various pH were conducted at optimum contact time.\ud From the results, it was clear that the adsorption capacity at pH of 7 > pH of 4 > at pH of 10 and\ud adsorption followed isoterm Freundlich
