spent catalyst

The developed biosorbent SC was used in this study The removal efficiency of the biomass in different ratio of the biomass and copper,pH value,temperature and time was studied The experimental result showed that the removal efficiency to printed circuit board of different Cu 2+ concentration reached 95 48% and 86 74% on the discovered optimum condition

用研制的SC菌剂作生物吸附剂 ,研究了其在不同菌铜比 ,pH、温度及作用时间条件下对Cu2 + 的去除效果。

The experiment results show that the effect of SC modifier is excellent and ultra-low carbon ductile iron with round sphere, a small number of uniformly distributed small graphite spherule and matrix structure without carbide can be got after modifying treatment by using SC modifier.

试验结果表明,SC变质剂变质效果最好,能够在铸态得到圆整度好、数量少、分布均匀的细小石墨球,并且基体组织中不存在碳化物。

The best thickness range of the mechanical test sample of the SC-13 adhesive is 4.

研究了热强-290纤维/SC-13改性酚醛树脂复合材料的力学试验设计与试样厚度对其力学试验数据的影响,确定SC-13粘结剂的力学测试试样的厚度的最佳范围为4。
