中文摘要 | 研究了利用电子束辐照降解氰化钠水溶液的效果.分别考察了CN-初始浓度、溶解氧浓度、辐照剂量率对CN-降解效果的影响.采用总有机碳(TOC)分析仪、离子色谱仪(IC)、紫外分光光度计等分析了CN-在不同实验条件下的辐照降解产物.实验结果表明,电子束能有效降解水溶液中的CN-,较低的CN-初始浓度,较高的辐照剂量,较高的溶解氧浓度以及较低的辐照剂量率能够提高CN-降解效率.CN-辐照后转化为NH3、NO-3、NO-2、碳酸盐和有机物.; Degradation of sodium cyanide in aqueous solution by electron beam irradiation was studied with radiation doses up to 48 kGy.The effects of initial CN-concentration,dissolved oxygen concentration and dose rate on the degradation of CN-and the identity of its degradation products were examined by total organic carbon analysis,ion chromatography and ultraviolet spectrophotometry.The results showed that lower initial concentrations,higher irradiation doses and lower dose rate increased the degradation.Increasing the concentration of dissolved oxygen in the solution increased the effectiveness of CN decomposition-.The degradation products after irradiation were NH3、NO-3、NO-2、carbonate and organic substances. |
