DETERMINATION OF CADMIUM (Cd) CONTENT IN COMPOST TPA AND STUDY OF ITS ACCUMULATION IN KANGKUNG (Ipomoea reptans) AS ONE OF PHYTOREMEDIATION
A study of cadmium content in compost from TPA in Sukabumi was carried out. The technique of random sampling was realized. From 10 sampling areas, we took each of three parts of sampling areas, to represent well the population, i.e. the upper, the center and the bottom parts. Compost samples were us...

| Summary: | A study of cadmium content in compost from TPA in Sukabumi was carried out. The technique of random sampling was realized. From 10 sampling areas, we took each of three parts of sampling areas, to represent well the population, i.e. the upper, the center and the bottom parts. Compost samples were used as culture media for growing kangkung darat (Ipomoea reptans). Kangkung, was cultivated in cadmium unpolluted from the air. Kangkung was harvested for three periods: one month, two months, and three months of cultivation. The cadmium content was determinated in root, stem and leaves part of kangkung. All the samples were digested using HNO3 1:1 for 12 hours, and then continued with 30 minutes heating at 105oC and finally hydrogen peroxide was added to completion of the oxidation reaction. Method validation was done to determine % recovery using two calibration methods: external and addition standard calibrations. It was obtained that % recovery for both methods were 97.05 % and 120.0%. <br />
