Synthesis of Poly(Acrylic Acid) Based Polymers as Quantitative Determined Scale Inhibitor


In present days, the use of water transported from the river as the source material for generating electricity is very common. Generally, this water needs to be purified before it can be used in the process. However, during the water purification process, some calcium ion that existed is not uncommon. The calcium ion will somehow create some dregs when absorbing enormous heat, thus adding polymer to capture the calcium ion is necessary. In this research, we focused mainly on the synthesis of poly (acrylic acid) (PAA) as the material to eliminate the dregs by reducing the Calcium carbonate and Calcium sulfate in the water cooling system. Comparison can be made by the length of Polymer Structure PAA-1, PAA-2, PAA-3 and PAA-4 in the solvent as well as adjustment for the mole ratio of potassium persulfate which is used as the initiator. Then, we can further analyze the structure by using FT-IR technique, resulting in the missing of double bond (C=C) of AA monomer in the 1640-1680 cm-1 wave length interval, and turn to be single bond in the main structure of PAA. This result reflected that the synthesis can truly produce polymer. With that, we can further analyze the ability to eliminate dregs by using titration technique with PAA-1, PAA-2, PAA3 and PAA-4 at the concentration of 20 ppm, with high preventive percentage of 72%, 81%, 100% and 90% accordingly. The test result clearly shows that low concentration can perform better in eliminating dregs.
