Abstract

The adsorption of cadmium (Cd2+) by palm shell carbon (Arenga pinnata) activated carbon have been researched. This research is aim to find the effects of pH value, contact time and concentration. In this research, the variations of pH value was (2 – 7), contact time (5 – 70 minutes) and concentration (1,5 – 3,5 mg/L) were applied. The determination of cadmium concentration used an Atomic Absorption Spectrophotometer (AAS). The result of this research shows that pal shell activated carbon could adsorp metal ion Cd 2+ . The optimum condition was achieved at the pH 3 with a capacity factor of adsorbent was 2,372 mg/L or 94,92%, contact time was 30 minutes with a capacity factor of adsorbent was 2,327 mg/L or 93,12% and concentration was achieved at the concentration 3,5 mg/L with a capacity factor of adsorbent was 3,321 mg/L or 94,91%.Keywords: adsorption, actived carbon, palm shell, metal ions Cd 2+

Abstract

Telah dilakukan penelitian tentang analisa Pb(II) pada lobster (Panulirus sp) dengan metode adisi standar spektrofotometer UV-Vis menggunakan pengompleks ditizon. Penelitian ini bertujuan untuk mengetahui kadar ion logam Pb(II) pada lobster (Panulirus sp) dengan metode adisi standar menggunakan pengompleks ditizon. Analisa kadar ion.logam Pb(II) dengan pengompleks ditizon menggunakan spektrofotometer uv-vis sebelum menggunakan metode adisi standar. Hasil penelitian menunjukkan bahwa kadar ion logam Pb(II) sebesar 0,215 ppm sedangkan pada penelitian menggunakan metode adisi standar kadar Pb(II) sebesar 1,210 ppm.Kata Kunci: Lobster, Adisi Standar, Ditizon, Ion logam Pb(II).
