Paper Title:
Scale and Corrosion Inhibition of Synthesized Polymers from Waste Itaconic Acid
  Abstract

The itaconic acid polymers of low molecular weights were prepared from itaconic acid wastes. The waste solution was distillated under vacuum of 2.00 kPa and temperature of 40-90 °C to reclaim the used solvents. The remains were neutralized by NaOH, initiated by 5 wt. % potassium persulfate under nitrogen protection and polymerized in water for 12 h at temperature of 100-102 °C in consequence to prepare the itaconic acid polymers. The scale inhibition efficiency could reach 99.51% with a polymer amount of 15 mg/L in the water sample with Ca2+ and HCO3- concentrations of 240 mg/L and 732 mg/L. The corrosion inhibition efficiency of polymers could reach 97.89% in the industrial circulating water with Ca2+, alkalinity and total hardness of 480 mg/L, 341 mg/L and 598 mg/L (all calculated in CaCO3 content). The biodegradation rate of polymers could attain 82.11% in the microorganisms environment at 35 days of operation.
