resin (SIR) was prepared and applied in Cr(VI) removal. The morphology and the thermal stability of the resins were explored. The effects of equilibrium time and initial pH value on Cr(VI) adsorption were... ions separation [19,20]. Compared with liquid-liquid extraction, solid-liquid extraction provides an effective method for ILs application in separation. When ILs are immersed into the macroporous resins......
exchange was proposed. Various resins’ selectivity was studied in scandium chloride solution. The results indicated that D851 resin had high selectivity of Sc at low acidity, and high selectivity of Zr... than other approaches [15–19]. According to different forms of scandium in solution, different types of resins can be adopted to extract or enrich Sc [20–23]. Sulfonic cation- exchange resins......
and FT-IR. The results show that chemical reactions occur between waterborne epoxy resins and cement hydration products, the complex compound with calcium is produced, and the Ca(OH)2 crystallizing......
(Ⅲ)-loaded and Y(Ⅲ)-loaded IR124 resins are found to adsorb fluoride rapidly and effectively. The adsorption capacity of fluoride ion for different metal(Ⅲ)-loaded IR124 resin is in the order of Ce(Ⅲ)>......
reduced to Ce(III) and the reduction percent of Ce(IV) increased with shaking time increasing.But RNO3 was morestable than other resins due to the high resistance to oxidation.A little increase......
Properties of a New Dental Photocurable Matrix Resin with Low Shrinkage付静State Key Laboratory of Oral Diseases,West China College of Stomatology,Sichuan University摘 要:In order to reduce the amount of volumetric shrinkage that occurs in dental composites as......
Preparation and Characterization of Carboxyl-terminated Poly(butadiene-co-acrylonitrile)-epoxy Resin Prepolymers for Fusion-bonded-epoxy Powder Coating刘敬成,刘晓亚School of Chemical & Material Engineering,Jiangnan University摘 要:Liquid carboxyl-terminated poly(b......
on the thermal stability, toughness and hydrophobicity of PFASO/epoxy complex. The experimental results reveal that epoxy resins can be successfully modified by adding a small amount of as-synthesized modifiers......
properties analysis of curing films showed that the impact strength and fracture toughness increased significantly upon the addition of PBG, indicating good toughness of the modified epoxy resins. From......
