Caecilia, Pujiastuti and Erwan Adi, Saputro (2011) ADSORPTION OF Pb IN ELECTROPLATING WASTE WATER by MORINGA SEEDS POWDER. In: Bali Internasional Seminar on science and technology 2011, 22-23 july 2011, Bali.
One of the industries that produce liquid waste that is hazardous electroplating industry. Liquid waste generated mostly still contain high levels of metals, including metal content of lead (Pb). One way to wastewater by biosorption is a process ofadsorption by usingbiomass as an adsorbent. Moringa seeds are dried peeled and crushed with a size of 80mesh. Furthermore, moringa seed powder as much as 2 grams inserted into erlemeyer containing 100 ml of liquid waste with a specific pH, then whipped with a shaker in accordance with thevariable contact time. The filtrate obtained was analyzed. The variable in this study: wastewater pH(4,6,8,10,12) and contact time (5,15,25,35,45) minutes from the results, the best pH was at pH 4 and the contact is the best time is in 35 minutes with% removal 94.71%.
