A IAS degradation strain with high resistance, which could take linear alkylbenzene sulphonate (LAS) as only carton origin for growth, was isolated from the drain canal of Hangao Detergent Plant of Xuzhou. The characteristic of its degradation was researched and the results showed that the optimum conditions of this strain for degrading LAS were 30℃, pH 6.0, 150 ml solution in 500 ml triangle vase, 120 r/min, LAS concentration of 200 - 600 mg/L. The growth amount of the bacteria were up to 0. 443 ( OD400 ) and the degrading rate was up to 89.4%. The ability of the bacterium to degrade LAS could be as high as concentration of 1 200 mg/L. 展开更多

本文以十二烷基苯磺酸钠(SDBS)作为主要实验样品,利用偏振二向性反射光度计探究不同浓度的直链烷基苯磺酸盐(LAS)的偏振反射光谱特性与探测方位角、光线入射天顶角、探测天顶角、偏振角、波段间的关系,并与一种家用洗衣粉及蒸馏水的偏... 本文以十二烷基苯磺酸钠(SDBS)作为主要实验样品,利用偏振二向性反射光度计探究不同浓度的直链烷基苯磺酸盐(LAS)的偏振反射光谱特性与探测方位角、光线入射天顶角、探测天顶角、偏振角、波段间的关系,并与一种家用洗衣粉及蒸馏水的偏振反射光谱曲线作比较.结果表明,LAS溶液的浓度、观测时的几何条件和波段是影响LAS溶液偏振反射光谱特性的主要因子,而且不同LAS浓度间的偏振反射光谱特性会随着观测时的几何条件与波段的变化而出现明显差异,这为偏振遥感在环境上的应用奠定了实验基础. 展开更多
