通过一个简单的合成方法制备了基于柔性苯并咪唑的含钴金属有机骨架[Co（L）（tp）]n （L=1，3-二（5，6-二甲基苯并咪唑基）丙烷， H2tp=对苯二甲酸），研究了该材料对刚果红的吸附作用和吸附模型。实验结果表明： pH为5.5，吸附剂浓度为0.16 g/L，反应温度为45℃，吸附120 min，刚果红溶液的脱除率接近100%。[Co（L）（bdc）]n对刚果红染料的吸附较好地符合Langmuir等温模型。

A new facile method for the synthesis of cobaltic metal-organic framework[Co(L)(tp)]n based on the flexible bis (benzimidazole) was developed ((L=1,3-bis (5,6-dimethylbenzimidazole) propane, H2tp=terephthalic acid) . The effect factors and adsorptive isotherm model of adsorptive removal of Congo red azo dye by[Co(L)(tp)]n were investigated. The result showed that pH value of 5.5, adsorbent of 0.16 g/L, temperature of 45℃, by reaction time 120 min, about 100% Congo red dye was removed. The adsorption processes of Congo red fitted Langmuir isotherm model excellently.
