活性位点的增加是提高无机/有机杂化吸附剂吸附性能的重要因素，而无机配体的选择与调控是增加吸附剂活性位点的关键因素。项目组前期成果表明，无机骨架材料的不同既可以调节吸附剂稳定性，又可以实现活性组分的最大化固载。鉴于此，我们提出如下假说：无机骨架材料对无机/有机杂化吸附剂的实际应用具有重要的调控作用。本研究拟选择难溶于酸碱的硫酸钡作为无机骨架材料，通过原位杂化固载直接染料废水，进而制备阳离子染料废水处理的高效吸附剂。通过各种分析技术和测试手段测定吸附剂的组成，表征吸附剂的结构，利用langmiur、Frendlich等模型阐明吸附剂的吸附机理，揭示硫酸钡原位杂化染料的发生机制以及硫酸钡提高吸附剂吸附性能的原理，探究吸附剂制备及阳离子染料废水处理的最佳工艺参数，建立直接染料废水与阳离子染料废水协同治理的新方法，为高浓度有机工业废水的环境友好处理进行有益的尝试性研究。

The increase of the active sites is an important factor to improve the adsorption properties of inorganic/organic hybrid adsorbent, and the selection and regulation of the inorganic ligand is the critical factor to increase the active sites of the adsorbent. The previous results indicated that the different inorganic framework materials can not only adjust the stability of the adsorbent but also achieve to maximize immobilized of the active component. Therefore, we propose the following hypothesis: inorganic framework has an important role in the regulation of the practical application of inorganic/organic hybrid adsorbents in wastewater treatment. The objective of this work is to establish a new-type wastewater treatment method by in situ hybriding waste direct dyes into a harmless inorganic skeleton BaSO4 for preparation the high effective adsorbent for treatment the cationic dyes wastewater. The morphology, composition and structure of the hybrid adsorbent will be characterized and tested by by a variety of analytical techniques and testing means. The occurrence mechanism of barium in situ hybriding dyes will be elucidated. The mechanism of adsorption of pollutants will be clarified by using the Langmiur and Frendlich isotherm for fitting or the other's interaction law. The effects of inorganic ligand on adsorption properties will be revealed. The project will deeply investigate the optimal synthesis conditions of the adsorbent and the optimum process parameters of treatment cationic dye wastewater. This work will provid a convenient, cost-effective and environment-friendly wastewater treatment with "Using Waste to Treat Waste" for the large-scale production of a cost-effective sorbent. The project will lay a useful theoretical basis for the environmentally friendly processing of the high concentration of organic industrial wastewater.
