The Synthesis Of Complex Functional Resin And The Study Of Phthalate Monoesters Water Pollution Control

The resin for the removal of phthalic acid monoesters processes have been closer to the popular, which is also one of the most effective way.By comparing the high cross-linked resin adsorption properties of phthalic acid monoesters, and activated carbon adsorption properties of phthalic acid monoesters, this study is aims to the synthesis of novel composite functional resin. Furthermore, the study is also on the pinned hope of developing a basic process, which is depended on a deep purification of the phthalic acid monoesters micro-polluted water bodies, by researching the joint removal performance of the new composite functional resin mono-butyl phthalate-electrostatic adsorption wih the dual function. In this thesis, the following aspects are contanted:First of all, the thesis studies two kinds of adsorption material with alkaline groups, that is, D201and D301,by contrasting their capacity of adsorption-removal of the two adsorption material of phthalic acid monoesters.In313K conditions, D301, on the MBP has a higher saturation adsorption of about420.3mg.g-1,the D201of MBP saturated adsorption amount of1.6times, in the288K-313K temperature range increased temperature will help improve the two adsorption material the adsorption capacity of the MBP. D301and D201on the MBP has a high removal rate and removal efficiency of90%in200min. Two adsorption material removal rate on the MBP is basically the same.In this study, we are also trying to using two kinds of adsorption of pure physical adsorption material—the ultra-high cross-linked resin SD300in adsorption of phthalic acid monoester and the common adsorption material activated carbon. under the298K conditions, the SD300saturated adsorption of about MBP higher than the saturated adsorption capacity of activated carbon on the MBP is228.4mg/g than224mg/g, increases with increasing temperature adsorption capacity of the two adsorption material for MBP. Under the same conditions, the SD300removal rate of MBP was slightly lower than the activated carbon.Based on the data and results of the previous investigation and study, we can synthesize a complex function of resin, that is the JAS-200. under the313K conditions, the saturated adsorption capacity of the JAS-200of MBP for the348mg/g and; column adsorption and desorption experiments show that, thefirst150BVwithin the effluent concentration of MBP below the detection limit of10μg/L,the desorption agent under of20BV the resin after the adsorption of MBP desorptionrate close to100%, indicating that the complex functional resins with good regeneration performance.In summary, the synthesis of complex functions resin JAS-200as a complex function of adsorbent, which can show the depth of removal of pollutants in water phthalic acid monoesters good prospects. This thesis is an important theoretical and technical foundation for the development of resin catalyzed removal of the technical depth of removal in water phthalic acid monoester.
