Pengaruh Perlakuan Fisi dan Kimiawi Zeolit Alam Lampung Terhadap Kapasitas Jerap Ion Amonium

Natural zeolit from lampung(Zal) which contains 75% of clinoptilolite structure is supposedly useful for wastewater treatment by adsorption process.The Adsorption capacity of natural zeolite is usually less than that of synthetic zeolite due ti it contasins other minerals such as calcite, gypsum, felspar etc.physical or chemical treatmen of natural zeolite is needed to improve its adsorption capacity. the effects of physical and chemical treatment of zal on the adsotrption caqpacity of ammonium ion have been investigated experimentally in this study.Physical treatmens were done by cacination while the chemical treatments done by washing zal using naoh or h2so4 solutions.the parameters studied in this experiment were calcination temperatures and concrentrations of the solution.The zeolite used in this experiment was in the size of 8 to 10 mesh, the initial concentration of ammonium ion in the solution was 1 g/l, and the ratio of zeolite to solution was i g to 10 ml. The experimental result show that the highest adsorption capacity of the calcinated zeolite is 1.9922 mg nh+ per g of zeolite for the calcination temperature of 300 c.The adsorption capacity for zeolite treated by naoh solution is higher than that of h2so4 solution.The highest adsorption capacity for the three different treatment is 2,117 mg nh4+ per g of zeolite that is for the treatment using naoh solution
