The solid waste management problems caused by the accumulation of plastics require measures to mitigate the environmental damage, and mechanical recycling of plastics is among the possible solutions. In this context, the present study aimed to evaluate the effects...

Microwave-assisted synthesis and characterization of hydrophilically functionalized polygalacturonic acid.

Carbohydrate polymers

Mohd Aris ZF, Bouldin RM, Pelletier MG, Gaines P, Budhlall B, Nagarajan R.
PMID: 27702532
Carbohydr Polym. 2017 Jan 02;155:432-439. doi: 10.1016/j.carbpol.2016.08.070. Epub 2016 Aug 22.

Microwave-assisted synthesis of a new class of polymeric surfactants based on polygalacturonic acid (PGA) is presented. PGA is water-insoluble and not surface-active under normal conditions. Single-step hydrophilic modification of PGA with taurine (2-aminoethane sulfonic acid) renders it surface-active. The...

Plastic Classification with X-ray Absorption Spectroscopy Based on Back Propagation Neural Network.

Applied spectroscopy

Wang Q, Wu X, Chen L, Yang Z, Fang Z.
PMID: 28485652
Appl Spectrosc. 2017 Nov;71(11):2538-2548. doi: 10.1177/0003702817706921. Epub 2017 Sep 12.

Currently, spectral analysis methods used in the classification of plastics have limitations that do not apply to opaque plastics or the stability of experimental results is not strong. In this paper, X-ray absorption spectroscopy (XAS) has been applied to...

Plastics in soil: Analytical methods and possible sources.

The Science of the total environment
