Highly Efficient Adsorption of Cd(II) onto Carboxylated Camelthorn Biomass: Applicability of Three-Parameter Isotherm Models, Kinetics, and Mechanism J. Polym. Environ. (IF 2.572) Pub Date : 2020-12-07 A. Hashem, G. M. Taha, A. J. Fletcher, L. A. Mohamed, S. H. Samaha
A series of malonic acid treated camelthorn (MATC) sorbents were produced via the reaction of camelthorn biomass with malonic acid, and factors affecting the extent of modification were investigated, including malonic acid concentration, dehydration time and temperature. The optimum sorbent, by carboxylic acid content, was subsequently characterised for surface charge behaviour (pHPZC), surface chemical

Biosorption Characteristics of Cu(II) and Cd(II) Ions by Modified Alginate J. Polym. Environ. (IF 2.572) Pub Date : 2020-08-06 Tuğba Alp Arıcı, A. Safa Özcan, Adnan Özcan
In this study, a novel biosorbent was prepared by the modification of sodium alginate with thiosalicylic acid in the presence of calcium ions (TS-A). TS-A was then characterized and its removal performance for Cu(II) and Cd(II) ions from the aqueous solutions was investigated. The effects of batch and column parameters on the biosorption were systematically investigated. The obtained data from the

Modified Starches on the Properties of Extruded Biodegradable Materials of Starch and Polyvinyl Alcohol J. Polym. Environ. (IF 2.572) Pub Date : 2020-08-05 Juliano Zanela, Ana Paula Bilck, Mônica Oliveira Reis, Maria Victória Eiras Grossmann, Fabio Yamashita
This work aimed to study the effect of modified cassava starches, and PVA grade on the properties of biodegradables sheets produce with starch/PVA blends by an extrusion-calendering process; using native starch, distarch phosphate, acetylated distarch phosphate, acetylated distarch adipate or oxidized starch; PVA with 88% and 98% hydrolysis degrees (HD), and glycerol as a plasticizer. The sheets had

Degradation Urushiol Coating Composition Crosslinked by Diallyl Trisulfide J. Polym. Environ. (IF 2.572) Pub Date : 2020-08-04 Hanyu Xue, Yuchi Zhang, Xinzhong Li, Jianrong Xia, Qi Lin
Urushiol (UR) was a kind of natural paint with a long history and excellent performance. Its high price restricts its development. For the sake of the sustainable development of UR, we prepared a new urushiol based coating composition which is of degradation. To be more specific, we develop a blend by diallyl trisulfide (TS) and urushiol, in which a free radical copolymerization process would take
