Abstract

It has been studied the use of salak husk to adsorb of iron, cadmium, zinc, and copper. The salak husk, which has been grounded, screened and astivated" looked for optimum condition. Several parameter that can be affect iron, cadmium, chromium, zine, and copper uptake such as particle size of salak husk, pH, contacting time, concentration,the heating temperature and heating time of salak husk were described. At the optimal condition iron metal removal from aqueous solution is 94.58 7o, cadmium 93.38%, chromium 93.20 %, zinc 88.78 oh and coppff 80.30 % by using atomic absorption spectrophotometric. The method was applied to multi component solution giving adsorption in iron 95.68 7o, cadmivrrr 74.93 7o, chromium 85 .50o/o, nlllc 76.507o, copper 73.90 % and removal iron, cadmium, chromiurrg zinc, and copper present in Utama Senrice and Rarna Motor workshop Padang. Key word: Salak hush iron, cadmium, chromium, zinc, copper, atomic adsorption, spechophotometic, wastewater.
