Abstract

Kemampuan kulit kupang untuk adsorpsi ion logam tembaga dalam larutan dilakukan dalam kolom fixed-bed dengan diameter sebesar 1,5 em dan konsentrasi awal ion Cu(II) 20 mg/L. Percobaan dilakukan dengan menggunakan laju alir yang berbeda yaitu 0,5; 1; dan 2 ml/menit pada pH 4 untuk mendapatkan kurva breakthrough. Dua model kinetik yaitu Bohart-Adam dan Thomas digunakan untuk menentukan keefektifan adsorpsi No, konstanta kecepatan k dan konsentrasi maksimum q0. Dari hasil analisa terlihat bahwa semakin tinggi laju alir akan menurunkan waktu breakthrough dan kolom dengan laju alir 1 ml/menit memiliki harga q0 dan N0 yang paling tinggi yakni 181,2 mglg dan 4468,42 mg/1 dengan konstanta kecepatan k lx 10"" Lmg"1jam·1 yang mc:nunjukkan keefektifan dan kapasitas adsorpsi yang paling baik.

The ability of kupang shell to adsorb copper ion was investigated in fixed-bed column that had internal diameter 1.5 em and initial concentration was 20 mg/1. Experiments were performed using different flow rate i.e 0,5; I; and 2 ml/minute at pH 4 to obtain breakthrough curve. Two kinetical models were applied to determine adsorption effectiveness N0, Kinetic constant and maximum concentration Qo. The analytical data showed that the increase in flow rate decreased the breakthrough time. Column with the flow rate 1 ml/minute had the highest q0 and N0 value, i.e: 181,2 mglg and 4468,42 mg/1 with kinetic constant K 1x 10-4 Lmg-1hr-1 which indicated the best effectiveness and adsorption capacity.
