KAJIAN KADAR UNSUR KROM DALAM LIMBAH TEKSTIL DENGAN METODE AAN

Abstract

Has been identified Chrom unsure’s content in textile waste by Neutron Activation Analyze in Sukoharjo regency. The samples took as sediment and liquid. Samples irradiated by Lazy Susan irradiator, Kartini terrace, for along 11 hours and then it’ll counted by HPGe detector for along 300 seconds. The result of qualitative analyze show that it contains chrom (Cr-51) unsure. Quantitatively, chrom unsure’s content in once processed sediment sample is (156.34 ± 25.15 ) ppm, and in once processed liquid sample is (0.42 ± 0.06 ) ppm, and in ending waste sediment sample is (116.61 ± 18.31 ) ppm, and the last in ending waste liquid sample is (0.39 ± 0.21 ) ppm. Based on PP No. 82 Tahun 2001 chrom’s content inside liquid sample is still under water quality standard.
