Abstract

Logam berat berpotensi mencemari lingkungan diantaranya yaitu ion Pb2+, Cu2+, dan Zn2+. Pengolahan yang dapat dilakukan yaitu dengan metode adsorpsi. Penggunaan cangkang kerang darah (Anadara granosa) sebagai adsorben alternatif karena memiliki jumlah banyak dan persebaran luas di berbagai wilayah. Tujuan dari penelitian ini yaitu untuk mengetahui karakteristik cangkang kerang darah, kapasitas adsorpsi terbesar, isotherm, dan kinetika adsorpsi. Analisis karakteristik cangkang kerang darah menggunakan energydispersive X-ray (EDX). Kapasitas adsorpsi dianalisis berdasarkan ukuran butiran (0,14-0,29mm dan <0,074 mm) dan aktivasi (110oC, 550oC, dan H2SO4 0,5M) untuk mengetahui kapasitas adsorpsi terbesar. Isotherm adsorpsi dan kinetika adsorpsi didapatkan dari percobaan batch dengan variasi massa adsorben (0,1-0,5 gram) dan waktu adsorpsi (0,5-6 jam). Hasil dari karakterisasi cangkang kerang darah sebelum digunakan adsorben mengandung Ca, C, O, dan Na sedangkan setelah digunakan adsorben terdapat tambahan kandungan Pb, Cu, dan Zn. Kapasitas adsorpsi maksimum cangkang kerang darah yang digunakan untuk adsorpsi Pb2+, Cu2+, dan Zn2+ berturut-turut sebesar 125 mg/g (0,074mm; 550oC); 38,462 mg/g (<0,074mm; 550oC); 200 mg/g (0,14-0,29mm; 550oC). Isotherm dan kinetika adsorpsi berdasarkan kapasitas maksimum Pb2+, Cu2+, dan Zn2+ mengacu pada model Freundlich – Pseudo-second order. ================================================================================== Environmental pollution can be casuseed by heavy metals ion such as Pb2+, Cu2+, and Zn2+. One method that can be used to reduce heavy metals concentration is adsorption. Blood cockle shell (Anadara granosa) can be used as adsorbent alternative since it has very numerous and wide distribution in many areas. The objectives the research are to determine characteristics of blood cockle shell, adsorption capacity, isotherm, and kinetics. Analysis of the characteristics of blood cockle shell use energy-dispersive X-ray (EDX). Analysis of adsorption capacity based on grain size variation (0,14- 0,29 mm and <0,074mm size) and activation (110oC, 550oC, and H2SO4 0,5M)to determine the largest adsorption capacity. Adsorption isotherm and kinetic was obtain from batch experiment by varying mass of adsorbent (0,1-0,5 gram) and time of adsorption (0,5-6 hour). The result characteristics blood cockle shell show that before used for adsorbent contain Ca, C, O, and Na after used for adsorbent Pb, Cu, and Zn are stored in blood cockle shell. The maximum adsorption capacity blood cockle shell that used for adsorbent Pb2+, Cu2+, and Zn2+ were 125 mg/g (<0,074mm; 550oC); 38,462 mg/g (<0,074mm; 550oC); 200 mg/g (0,14-0,29mm; 550oC) respectively. The isotherm and kinetic adsorption based on maximum adsorption capacity Pb2+, Cu2+, and Zn2+ following Freundlich – Pseudo-second order.
