The aim of this study was to observe the effect of composition ratio of precursor and mass of ZnO-CuO for photodegradation of Linear Alkylbenzene Sulphonate. Material synthesis is done by solid stated process. The ZnO-CuO composite was characterized using DRS-UV and FTIR. The percentage of degradation was obtained from the absorbance value measured using a UV-Vis spectrophotometer. The ZnO-CuO composite photodegradation activity in 2: 1 ratio was 54.71% for 105 minutes irradiation. The degradation percentage of ZnO-CuO composites have higher photocatalytic activity than single ZnO (53.64 %) and CuO (52.21 %) semiconductors in degrading LAS.
