Sodium Lauryl Sulfat (SLS) and Alkyl Benzene Sulfonate (ABS) are anionic surfactant. SLS is usually contained in soap, shampoo, detergent, and other cleansers, meanwhile (ABS) is usually on of contained in detergent. Using SLS and ABS surfactant in daily activities produces wastewater which contains SLS and ABS surfactant that will be go into the environment. The presence of SLS and ABS surfactant in the water environment can disupt ecosystems such as reducing the dissolved oxygen by the presence of foam and can disrupt organisms breeding. A SLS surfactant wastewater treatment technology is needed to avoid the bad effect to the enviroment. Photocatalytic is one of solution to treat wastewater which contains surfactant especially SLS and ABS. The objective of this research is to determine the optimum conditions of photocatalytic process for SLS surfactant degradation and to know the performance of photocatalytic in surfactant SLS and ABS degradation. Photocatalytic process has done using UV-C ray with wavelength in range 200 – 280 nm and ZnO nanoparticle as the photocatalyst. ZnO nanoparticle photocatalyst was made by precipitation process and the SEM anaysis has been done to show that the ZnO photocatalyst has particle size in nano particle scale. The optimum condition of photocatalytic process was obtained by experiment using a batch reactor. The experiment has been done by doing three kind of variations, that are Zno nanoparticle concentration variations as 0,05; 0,1; 0,2; 0,4; and 0,8 g. ?????1, pH variations as 3, 5, 7, 9, amd 11, and process variations as just using ZnO nano particle, using ZnO nanoparticle and UV ray at the same time, just using UV ray, and without ZnO nanoparticle photocatalyst and UV ray. The result of the experiments show that the optimum condition of photocatalytic process is using ZnO nanoparticle photocatalysist and UV ray at the same time with ZnO nanoparticle concentration as 0,4 g. ?????1at pH 9. And photocatalytic process has a better performance in SLS surfactanr degradation than ABS surfactant degradation.
