- The aimof the research is to knowperformance of absorption characteristic on reduction of chromiumin the liquid waste electroplating industry. Using nanocatalyst TiO2 which was made as composite with adsorbents materials Precipitated Calcium Carbonat (PCC) and activated carbon. The experiments were carried out in a batch photo-reactor system equipped with UV lamps and magnetic stirrer. The activity of catalyst, adsorbents and nanocomposits were tested using 100 mg/L waste water from electroplating industry. The test was done by additions of TiO2, adsorbents (active carbon and PCC), TiO2-PCC and TiO2-active carbon for reduction of Cr (VI). The reduction phenomenon was analyzed by Atomic Adsorbent Spectrophotometer. The result shows that reduction of Cr (VI) by TiO2 was 66 % for 150 minutes, while by adsorbents were 56 % and 36 % for activated carbon and PCC, for 90 and 120 minutes, respectively. Moreover, using nanocomposite TiO2-activated carbon was 100 % reduction of Cr (VI) for 150 minutes and 95 % using nanocomposite TiO2-PCC for 300 minutes. The activity test results using waste water containing Cr (VI) as an organic waste shown that using both the activated carbon and PCC which were composited with TiO2 will increase the activity of catalyst. However using the activated carbon more effective than that of PCC.Keywords: Photoreduction, Chromium waste, TiO2, Activated Carbon, Precipitated Calcium Carbonat.
