| Abstract: | The dynamic growth process of CaSO4.2H2O crystal was studied byseeded crystallization of the supersaturated solution. The induction periods of CaSO4.2H2O crystal under the condition of adding nine different scale inhibitors have been determined. It was found that PAA and PMAAA had a better inhibiting action to the scale formation of calcium sulfate. The higher solution pH and the lower solution temperature, the higher their inhibition ability. The PAA or PMAAA of lower molecular weight showed much higher inhibiting ability. It has been demonstrated that the possible mechanism of scale inhibition is the adsorption of inhibitors on the active sites of the surfaces of crystal CaSO4.2H2O. The adsorption of PAA and PMAAA on the crystal surfaces accorded with the characters of Langmuir model. |
