This paper is concerned with the adsorption of Cr(III) by natural zeolite and polymeric Al/Fe (PAFC) modified one. The effects of the kind of zeolite, surging time, initial concentration of Cr(III), pH and ionic strength on the adsorption performance were investigated. Meanwhile, the adsorption capacities of zeolite were discussed. The results showed that the amount of saturated adsorption of PAFC...
In order to improve the adsorption capacity between polymer particles and abrasives in composite abrasive slurry, the adsorption characteristics of PDADMAC on BGF particles and changes of BGF particles' Zeta potential have been investigated. Two kinds of composite abrasive slurry were obtained with BGF particles before and after modified, and their polishing performance were studied by experiments...
A revised model based on Lattice-Density-Function Theory (LDFT) was built in this paper and was used to indicate the adsorbing behaviors of monomers in nano slits. This work tried to establish a theoretical model and get the fundamental mechanisms of the in situ-monomer-intercalation process which is the most common production method of polymer-layer silicate intercalated nanocomposite (PLSN). According...
A new polymer, oxidative Poly-Si-Fe (PSF) coagulant was prepared by an oxidization and copolymerization method. The influence of the oxidization of PSF on the adsorption of humid acid (HA) was explored, in comparison with that of polyferric aluminum (PFA). The results show that PSF changes the molecular structure of HA, leading to the improvement of adsorption of HA.
A highly selectively synthetic molecular imprinted polymer (MIP) sorbent for 17-B-estradiol was prepared using a non-covalent imprinting technique. The MIP polymers were synthesized in ethanol by using 17-B-estradiol as the template, 3-aminopropyltriethoxysilane as the functional monomer, HCl as catalyst. When compared with the nonimprinted polymer (NIP), the MIP displayed outstanding affinity and...
Interfaces between liquids and solids or gases play important roles in a number of different technologies and have thus been the main focus of many theoretical and experimental studies. The discontinuous nature of physical properties at interfaces makes it demanding to develop a general theory, and most existing theories are therefore based on macroscopic continuum equations. Now, for the first time,...
