摘要: 目前国外对碱式碳酸锌吸附海水中铀的报导较少,对其吸附海水中铀的反应级数及活化能测定的报导尚未见到。本文试图用三颈瓶反应器及分光光度法,测定海水中铀与碱式碳酸锌的反应级数及活化能,并获得较满意的实验结果。Abstract: At present,the information about absorption of uranium from seawater by basic zinc carbonate is Scarce and literature about the determination of reaction order and activation energy of basic zinc carbonate and uranium in sea water is not available.This paper attempts to tackle these problems by using threenecked flask and spectrophotomertry.Satisfatory results were obtained.Basic zinc carbonate absorbent was prepared and rapidly added into seawater under constant temperature and stirring.Samples of seawater were taken at intervals and the concentration of uranium was determined by spetrophotometry.The reaction order and activity energy were obtained from the experimental data treated with chemical kinetic methods.
