Effect of Impurities on the Precipitation of Aluminium Hydroxide

摘要: The effects of sodium carbonate and various organic salts on nucleation agglomeration aluminium hydroxide from caustic solution were studied in 250 ml plastic bottles placed a rolling bath arrangement where only gentle agitation the bottle contents resulted. presence appeared to have decreased rates solution. Plant liquors which contained numerous impurities showed significant reductions but increased hydroxide. Other organics introduced seemed had mixed effects, some boosting or while others produced opposite effects. Oxalates no either agglomeration.
