【 摘 要 】

This research are to find out the influence of adsorbent composition between rice husk and water hyacinth in decreasing of Pb2+ion in simulation liquid waste; the optimumcomposition of combination adsorbent of rice husk and water hyacinth charcoal on Pb2+ion adsorption; and theeffectivenessof SPS as a method to determine the decreasing level of Pb2+ion in simulation liquid waste by combination adsorbent of rice husk and water hyacinth charcoal in μg/L level. Rice husk and water hyacinth carbonization using muffle furnace at 350°C for 1 hour. Rice husk charcoal activation in a 2 N NaOH solution and water hyacinth charcoal activated in a 5 M HCl solution. Contacting the combination adsorbent of rice husk and water hyacinth charcoal with a Pb2+solution with variation of mass composition, 1:0 ; 0:1 ; 1:1 ; 1:2 and 2:1. Analysis of the Pb2+ion level using SPS method. Characterization of rice husk and water hyacinth charcoal using the FTIR. The results showed that the combination adsorbent composition of rice husk and water hyacinth charcoal have an impact on decreasing Pb2+ion level. The optimum composition of combination adsorbent of rice husk and water hyacinth charcoal on the adsorption Pb2+ion is 1:2. SPS is an effective method to determine the decreasing Pb2+ion in simulation liquid waste from the adsorption process by combination adsorbent of rice husk and water hyacinth in μg/L, with Limit of Detection (LOD) was 0,06 μg/L.
