摘要： The cross-linked polyzwitterion/anion for the removal of strontium from aqueous solutions is a polyzwitterion having the following structure: and the corresponding anion formed by treating the polyzwitterion with a base, e.g., sodium hydroxide. The cross-linked polyzwitterion/anion (CPZA) was prepared using Butler's cyclopolymerization protocol. The CPZA resin was found to have a very good adsorption capacity for Sr2+ ions at low concentrations. The relatively strong rapid initial adsorption of 83% Sr2+ ions was followed by slower adsorption of the remaining 17%, which was described by an intraparticle diffusion model. The adsorption followed the Lagergren second-order kinetic model, and Temkin as well as Freundlich isotherm models. The negative ΔGs and ΔH ensured the spontaneity and the exothermic nature of the adsorption process. The excellent adsorption and desorption efficiencies implied the efficacy of the resin in removing (as well as recovering) the metal ions from aqueous solution.

摘要： The polyzwitterionic acid antiscalant is an antiscalant for use in desalination plants and the like for inhibiting CaSO4 and SO42− scale precipitation. The polyzwitterionic acid (PZA) antiscalant has the following structural formula: In order to make the PZA antiscalant, N-carboethoxymethyl-3-(N,N-diallylamino)propanesulfonate, a zwitterionic monomer, is cyclopolymerized in aqueous solution using tert-butyl hydroperoxide (TBHP) to make an intermediate polyzwitterion (PZ). Acidic hydrolysis of the ester groups of the PZ is performed to produce the PZA antiscalant. Evaluation of the antiscalant properties of the PZA antiscalant using concentrated brines revealed that the PZA antiscalant, at a concentration of 10 ppm, is very effective in inhibiting the formation of calcium sulfate scale, particularly in reverse osmosis plants.
