Sani, - (2010) KAJIAN AWAL PENURUNAN KADAR TIMBAL DAN KROM DENGAN MENGGUNAKAN BATUBARA DALAM REAKTOR PIPA. In: Seminar Nasional Teknik Kimia SOEBARDJO BROTOHARDJONO : “ Ketahanan Pangan dan Energi “, 24 Juni 2010, Surabaya.
Adsorption is a process that can be used for wastewater treatment because of the its not too complicated, as it also adsorbs readily available materials for and the cost low-cost operations. Many materials can be used as a absorbent one of which is coal. In addition to coal as a fuel can also be used as a pengadsorbsi. The purpose of this study was to determine how much capacity in the lower lignite barubara heavy metals Cr (chromium) and Pb (Lead) pipe in the reactor. Adsorption process is done by electroplating waste stream into the tank a pipe reactor which contains coal as adsorbent with a continuous flow. in This research will study the effect of coal as an adsorbent to reduce the concentration of metals weight of chromium and lead in a pipe reactor (column) in the range of the variable flow rate as the following: High bed (Cm): 25, 30, 35, 40, 45. Flow rate (ml / min): 35, 50, 65, 80, 95. The results of this study indicate that the decrease in the concentration of chromium metal is best for 7.343 mg / L with the% removal of 64.406% and a decrease in metal concentrations of lead that is best of 0.216 mg / L with the% removal of 40.659%, this result is achieved at a flow rate of 35 ml / min with the column bed height of 45 cm.
