The research in adsorption and desorption of nitrogen and phosphate is crucial to application of fertilization and environmental pollution prevention.

研究土壤对氮、磷的吸附/解吸附特性对合理施肥、防止环境污染等有重要的作用。

SEM result indicates that the mycelium on the surface of ectoblast of Nocardia cell is the important attachable site. IR spectrum shows that the functional groups such as —OH,—NH2, C==O, P==O, S==O, etc make vital contribution on adsorption process.

扫描电镜检测结果表明,诺卡氏菌细胞表面的菌丝是重要的吸附部位;红外光谱分析结果表明,诺卡氏菌表面含有—OH、—NH2、 C==O、 P==O、 S==O等活性官能团,它们在吸附过程中起重要作用。

Adsorption behavior of NB showed that the relationship between the adsorption amount of NB on the soil particles and the equilibrium concentration in solution was well linear within the concentration ranging from 0 to 25 mg/L.

2硝基苯在土壤粒子上的吸附实验表明:在0-25 mg/L浓度范围内,硝基苯在土壤粒子上的吸附量与溶液中平衡浓度之间存在较好的线性关系,表明硝基苯在土壤中的吸附机理以分配作用为主。

In this work the effects of the microporosity and chemical surfaceof polymeric adsorbents on adsorptive properties of phenol wereinvestigated.

译文在这工作,微孔性和化学制品 surfaceof聚合物吸附的作用在酚吸附物产wereinvestigated。

The paper is concerned with its experimental study on the mechanism and effect of Nocardia amarae used as adsorbent for removing Pb2+ from the waste water by way of biosorption-flotation.

以苦味诺卡氏菌作为Pb2+吸附剂,研究了采用生物吸附-浮选法去除废水中Pb2+的效果及其作用机理。

它不仅具有磺化萘等传统减水剂吸附在水泥颗粒表面使其表面带电而互斥作用,更具备支链的位阻作用,从而对水泥分散的作用更强,作用时间更持久。

Surfactant sorbed on soil increases the adsorption capacity of the soil; however, the microemulsion composed of surfactant and organic materials decreases the adsorption capacity of the soil.

增加离子强度对非离子表面活性剂的吸附无影响,却可略微增加阴离子表面活性剂的吸附。表面活性剂吸附于土壤后对憎水性污染物在土壤/水间的分配行为产生显著作用。

The aniline HDN was strongly stressed by the presence of quinoline and DHQ and the HDN of quinoline proceeds exclusively via a pathway which involves fully saturated intermediates on the MCM-41-supported nickel phosphides. The HDN activity of nickel phosphide catalyst was dramatically reduced by the presence of H2S and DBT, probably due to the strong adsorption of H_2S and DBT on active sites which inhibited the adsorption of quinoline.

喹啉和DHQ对苯胺的HDN反应有强烈的抑制作用,喹啉在磷化镍催化剂上几乎全部通过完全加氢饱和路径进行反应。H_2S和二苯并噻吩强烈地吸附在磷化镍催化剂活性中心上,阻碍了反应物分子的吸附,从而对喹啉的HDN反应有强烈的抑制作用。

The objective of this study was to compare and differentiate the different removal mechanisms of the dissolved organic matter in the secondary effluent during the granular activated carbon adsorption, horizontal subsurface flow wetland treatment, sand column treatment, laboratory-scale soil aquifer treatment and GAC+SAT.

通过模拟活性炭吸附、砂柱处理、土壤含水层处理、GAC+SAT及潜流式人工湿地处理实验,研究了城市污水处理厂二级出水中溶解性有机物在吸附、生物降解及生物与吸附的共同作用等具有不同DOC去除特点的处理过程中的去除及转化机制。
