ESTHI KUSDARINI, DIAN YANUARITA PURWANINGSIH AND AGUS BUDIANTO

Abstract

Some people in the city of Pasuruan, East Java, Indonesia still use wells water to meet the needs of clean water. Some of the well water samples contain Pb2+ ion of 0.15-0.23 mg·L-1. This level exceeds the maximum limit of clean air requirements in Indonesia Standard Ministry of Health Regulation No. 416 of 1990, maximum Pb2+ ion level 0.05 mg·L-1. The purpose of this research is to know the adsorption efficiency of IR 120 Na amine resin on Pb2+ ion; The isotherm condition of Freundlich and Langmuir. The study was conducted in three stages: 1) analyzing the physical properties and chemical content of samples; 2) processing the air in a cation exchanger processing installation; 3) analyze the content of Pb2+ ions processed air. The results showed that Pb2+ ion adsorption by IR amberlite resin 120 Na was 90.87-99.57%; In the use of resin mass of 20-100 g and feed rate of 0.0208-0.0435 L·s-1 showed that the Pb2+content of the processed air has met the standard. Adsorption of Pb2+ ions by isotherm with equations of Freundlich and Langmuir equations. Freudlich equation constant is n = 1.6943 and Kf = 6.9984 with result of 0.9715. Langmuir equation constant is As = 0.0175 and Kb = 136.8363 with research result of 0.8863.
