    查看更多>>摘要：Based on the review of 115 literature items, the article presents biopolymers as renewable polymer materials for sustainable development. The types of biopolymers and their applications are discussed, including biopolymers based on starch, cellulose, bacteria, soy and natural polyester. It also describes the issues of biocompatibility, the principles of sustainable chemistry and sustainable development, as well as market trends and future application directions.

The super-Nernstian slope of the projected sensor was 19.5 mV per decade over a concentration range of 7.3·10~(-8)-1·10~(-1) M having detection limit at 7.3·10~(-8) M. The sensor displayed a linear potential response for the detection of Fe~(3+) ions in about 30 seconds, and it had a lifespan of no less than 9 weeks without lacking any potential divergence. The selected sensor showed high selectivity in water solutions in relation to Fe~(3+) ions, even in the presence of other metal cations in the pH range of 3.6-10.

The reaction time was set as 24, 48, 72, 96, and 120 hours. The structure and optical characteristics of nanocomposites were analyzed using Fourier-transform infrared (FTIR) and ultraviolet-visible (UV-Vis) spectroscopy, respectively. Reaction time affected prepared nanocomposites by decreasing the intensity of the P3HT/MWCNT-OH peaks gradually with increasing of the reaction time. Comparing with the pure P3HT and MWCNT-OH, the calculated energy band gap and the Urbach energy of the nanocomposites were reduced proportionally as the reaction time reached 120 hours and achieved 2.60 and 0.329 eV, respectively.

    查看更多>>摘要：A new ion-exchange resin was obtained by incorporating a tripropylamine group into a tamarind polysaccharide resin (TTA). The TTA resin was characterized by FTIR, elemental analysis, and other physicochemical properties. The influence of pH, treatment time and resin concentration on the adsorption of metal ions from industrial wastewater was investigated. It was found that the obtained TTA resin effectively removes heavy metal ions in the following order: Fe~(2+)>Cu~(2+)>Zn~(2+)>Cd~(2+) Pb~(2+).
