This paper presents our research efforts in the discovery of pioneering synthetic routes and designing low molecular-weight maleic-anhydride (MA) homopolymers and MA-n-octyl acrylamide (AAO) copolymers (YMR-series) and their application as scale inhibitors for mineral scales. Hence, the solvent-free, eco-friendly, rapid microwave-assisted method has been developed for the first time to synthesize these antiscalants with higher yield and better efficiency. The inhibition ability on the CaSO4 and CaCO3 scale is 100 % with a 3 ppm dosage level at pH 10.45 and temperature 70 °C.Morphological changes of the CaCO3 and CaSO4 scales due to the strong inhibition action of YMR-series polymers have been studied by scanning electronic microscopy (SEM) and X-ray powder diffraction (XRD) analysis. It is also observed that the anti-scaling effect of the polymers greatly depends on the molecular weight, while MA copolymers show better inhibition efficiency compared to MA homopolymers. |
