Recent years, because of the development of the chemical spin and weave fiber objects, and the progress of the Neo-treatment skill, the waste dyed water contains great amount of PVA, reactive dye.etc, which are hard to dissolve by using organic methods, especially the reactive dye. Therefore, it becomes the urgent issue that to find out the highly efficient, low consumption, cheap price of solution for industrial field and recycling groups. This research is assumed to use 7 kinds of quatrnary amines, to change the properties of montomorillonite as absorbent, in order to make absorbing research on the most difficult disposition reactive dye, which contains the discussion of the reactive time, reactive temperature, the changes of quantitative usage of organic Montomorillonite, pH value.etc to see the influence of the absorbent reaction, and to find out the conditions of the best method of disposition of the dye wastewater. By the analysis of the XRD diffraction, after the changes of properties, the peak of the (001) move to left obviously. Therefore, to put the quatrnary amines into montomorillonite made the bigger spaced at interval, which was also analyse to prove the facts by DTA and TGA. After a series of absorbent research, the results reveal that the organic montomorillonite can almost absorb 100%of the dye wastewater, which proves that the interval of montomorillonite became bigger after properties changed by quatrnary amines, and the effect ion of deposition of reactive dye turns out very well. Meanwhile, the possibility of recycling the organic montomorillonite was discussed to reach the condition of the lower capital with highly economic effection.
