Anionic surfactant adsorption in detergent sewage with cation ion exchange method

Surfactant is one of chemical substances added in detergent. The surfactant type detergent anionic surfactant, namely Alkyl Benzene Sulfonate (ABS). a slow-degradable substance due to branched chain its structure, which causes low oxygen supply from the air foam covering water surface. This condition can cause dangerous impact for organisms water.This study aimed adsorb contained sewage using cation exchange resin. Before adsorption process, resin regeneration process was performed following standard operational procedures PT. Pertamina RU III, Plaju 4% H2SO4solution at time 45 minutes. occurred room temperature with mass variables 50, 100, and 150 g contact 5, 10, 15, 20, 25 Furthermore, content analyzed spectrophotometer 652 nm wavelength. analysis results showed that ion method 50 5 – minutes obtained capacity 0.72 g, while only 0.18 g.The best percentage achieved adsorbing up 100%. Meanwhile, closest equation assessment approach presented fromthe Langmuir isotherm model by gaining linear graphic R2 = 0.9946.
