   Sammanfattning : With a metal removal process based on precipitation aimed atthe purification of pulping effluent as a starting point, theinfluence of carboxylic acids on calcium carbonateprecipitation has been studied. The chosen carboxylic acids canact as more or less strong complexing agents for aqueouscalcium, just as many compounds found in pulping liquors. LÄS MER
