低浓度氢氟酸体系中MIBK萃取分离钽铌的研究

, 2012
开展了低浓度氢氟酸体系中MIBK萃取分离钽铌的研究,考察了萃取时间、萃取相比、氢氟酸浓度、钽铌浓度、钽与铌质量比对萃取分离过程的影响。结果表明,在始氢氟酸浓度0.5mol/L、钽铌总浓度60g/L、萃取相比(O/A)为5、钽与铌质量比2的条件下萃取5min可获得最佳的钽铌分离效果,钽铌分离系数高达50 ...

武汉东湖沉积物中酸挥发性硫化物(AVS)的深度分布及其影响因素

, 2003
沉积物中酸挥发性硫化物(AVS)是硫化物的生成、氧化和扩散等综合作用的反映,有机物的供给、硫酸盐的还原等因素都能影响其分布特征. 本文对武汉东湖三个污染程度不同站点的AVS深度分布特征进行了研究,结果表明,AVS含量在一定深度沉积物中具有最大值,东湖沉积物中AVS的深度分布具有两种不同的模式,I站和II站AVS浓度峰在5cm左右的表层沉积物中,且AVS还原层深度较狭窄,而III站AVS浓度峰处于10-20cm深度范围,沉积物中有机质负荷的差异是导致这种分布特征的重要原因 ...
