Studi Kinetika Adsorpsi Pb Menggunakan Arang Aktif Dari Kulit Pisang

Abstract

- Lead metal is one of environment polluter and can cause decease or health problems in sort time. The way to solve this problem is with used the carbon active from banana peel. This research is intend to find the kinetics model that appropriate in Pb adsorption process by knowing absorption of banana peel carbon active within mass variations (1; 1,5 and 2 g) and contact time (20, 40, and 60 minutes). Kinetics analysis are based from orde zero,one, and two and find the maximum capacity of adsorption from banana peel carbon active to lead metal. Equation which using at the adsorption process are Langmuir and Freundlich isotherm equations. From the analysis results, optimum time is at 60 minutes.kinetics of Pb absorption with carbon active from banana peel in mass 1 and 2 gr following kinetics model orde 2, then in mass 1,5 g following kinetics model orde 0. Langmuir equation is more appropriate in this research. Pb absorption from the banana peel that appropriate to Langmuir isotherm system is indicates adsorption was occur in one layer (monolayer). Maximum adsorption capacity is showing by the bigger value from a, that is 1,4582 in mass 1 g then interaction power of Pb with the banana peel was occur in mass 2 gr which showing with the value of kL is 0,4090
