Analisis Pengendalian Mutu dan Kadar Logam Timbal pada Gula Kristal Putih di Pasaran Menggunakan ICP-OES

Abstract

Quality testing and determining levels of lead metal contamination have been carried out in samples of white crystal sugar sold on the market using the ICP-OES method. This test was carried out to evaluate the quality of white crystal sugar on the market and to determine the effectiveness of the ICP-OES method for analyzing lead metal contamination in white crystal sugar samples. The results of testing the quality (quality) of white crystal sugar, namely 8 samples of white crystal sugar meet the provisions of ICUMSA SNI 3140.3: 2020, 15 samples (all samples) meet the provisions of the maximum SO2 content of SNI 3140.3: 2020, 13 samples meet the provisions for drying shrinkage (moisture content) SNI 3140.3: 2020 and 6 samples met the white crystal sugar polarization provisions of SNI 3140.3: 2020. Meanwhile for the 5 samples that were analyzed for lead metal contamination levels, all samples showed results that the lead metal content did not exceed the maximum limit of SNI 3140.3: 2020 and for the linearity test it showed the linear coefficient (R2) value is 0.9999; LoD results of 0.002155 ppm; LoQ results of 0.007183 ppm; The accuracy results are shown by the %Recovery value of 95.21% and the precision results are shown by the %RSD value of 1.95%.
