The changes in polychaete community were studied in the period of two weeks with results that though all concentrations did not basically altered the population structure and composition, the total biomass decreased significantly and individualstended to be smaller in size. The average weight of individual decreased with the increase of diesel pollutant stress.展开更多
采用红外光谱、低温N_(2)吸附-脱附方法对3种A型分子筛进行了表征,考察了3种A型分子筛吸附脱除模拟柴油中吡啶的性能,并进行了动力学研究。结果表明:在模拟柴油用量15 m L的条件下,3种A型分子筛吸附脱除模拟柴油中吡啶的最佳吸附剂用量...采用红外光谱、低温N_(2)吸附-脱附方法对3种A型分子筛进行了表征,考察了3种A型分子筛吸附脱除模拟柴油中吡啶的性能,并进行了动力学研究。结果表明:在模拟柴油用量15 m L的条件下,3种A型分子筛吸附脱除模拟柴油中吡啶的最佳吸附剂用量均为1.03 g,最佳吸附温度为50℃,最佳吸附时间为40 min;3种A型分子筛吸附脱除苯胺的性能均强于吸附脱除吡啶的性能,3种A型分子筛吸附苯胺和吡啶均符合准一级动力学方程。再生实验结果表明:焙烧再生优于醇洗再生;吸附吡啶的3种A型分子筛的再生率均高于吸附苯胺的分子筛。展开更多
