Selective Separation of Hg2+ on Modified Crosslinked Chitosan Beads Enriched with Amine Groups

Sodium tripolyphosphate crosslinked chitosan was prepared and immobilized with pentamine moieties. The samples obtained were characterized by elemental analysis and FT-IR. The adsorption behavior of the samples was studied towards Hg²⁺ using batch and column methods. The adsorption depended on the pH of the medium and was explained to proceed via complex formation and/or ion exchange mechanisms. The uptake capacity was found to be 4.7 mmol/g at pH = 2. Selective separation of Hg²⁺ from a solution containing Pb²⁺, Cu²⁺, Ca²⁺, Zn²⁺, Fe³⁺, and Mg²⁺ was achieved at pH = 1. The values of the kinetics and the thermodynamic parameters of the uptake process were reported. The flow rate of 3 mL/min in column experiments was found to be the most preferable rate. The regeneration of the loaded resin was performed using 0.5 M potassium iodide.     

Thermal,hydrolytic, anticorrosive,and tribological properties of alkyd‐silicone hyperbranched resins with high solid content

Novel alkyd hyperbranched resins (AHBRs) modified with a Z‐6018 silicone (a polysiloxane intermediate) and with high solid content were synthesized by etherification reaction using an acid catalyst. Different molar ratios of AHBR to silicone were used. Structural, thermal, hydrolytic, anticorrosive, and tribological properties were studied using infrared (IR) analysis, nuclear magnetic resonance (NMR), vapor pressure osmometry (VPO), thermogravimetric analysis (TGA), acid value, electrochemical impedance spectroscopy (EIS), and pin‐on‐disk friction. IR and NMR provide evidence of grafting of the silicone on AHBR; the efficiency of grafting was quantified by TGA. Thermal stability was studied also by acid value analysis. Grafting increases the number average molecular mass, enhances thermal stability, and improves significantly hydrolytic stability. Corrosion resistance on steel is improved by two orders of magnitude, hence our modified materials can be used as highly effective anticorrosion coatings. Grafting lowers dynamic friction dramatically, more so at higher concentrations of silicone. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
