Abstract: AA/AMPs poly(acrylic acid:2-acrylamido-2-methylpropane sulfonic acid) and PMA (polymaeic acid) are an important anionic polymer that are used as an anti-scalant in water cooling system. It contained a negative charge that severally used to prevent a scale formation and also has a good dispersion efficiency. During cooling operation involving water evaporation, concentration, blow-down, and make-up water. The concentration of the antiscalant has to be monitored in order for optimum dosing. In this work, a simple technique to determine AA/AMPs and PMA concentration was developed using complexing agent to the polymer that can then form large cluster for light scattering enabling rapid turbidity measurement. Here, benzethonium chloride or Hyamine, a large cationic molecule was used as a complexing agent for AA/AMPs and PMA to form a larger particle which can be detected via the UV-Vis spectroscopy technique. Turbidity was measured to confirm the complexation between these two types of chemicals. The result showed that Hyamine can be used for AA/AMPs and PMA concentration determination
