A new compound with biological activity had been synthesized by the reaction between 5-（p-chlorophenyl）-2-amino-1,3,4-thiodiazol and aroyl isocyanates.The structure of the target compound was confirmed by IR,UV,1HNMR spectrum and elemental analysis.The biological activity tests showed that the target compound had an activity as plant growth regulator,the auxin activity was 26.1% and the cytokinin activity was 41.1%.
[目的]使用柠檬酸和氢氧化钠对橙皮进行改性,对含有Cr6+的重金属废水进行了吸附研究。[方法]研究了溶液的pH值、溶液初始浓度、吸附剂用量、吸附时间及温度等因素对吸附的影响,并比较了酸改性和碱改性这2种改性橙皮的吸附作用。[结果]酸改性的橙皮对Cr6+有较好的吸附效果,在pH值为1.0左右,初始浓度5.0 mg/L,用量为0.6 g,温度50℃,时间为80 m in的条件下,酸改性橙皮对Cr6+的吸附率达到了96.52%。[结论]化学改性提高了橙皮的吸附能力,在废水处理中有很高的应用价值。
