TL;DR: In this article, a new strategy for the extraction and recycling of heavy metals by hydrothermal treatment is specifically emphasized, which is based primarily on the control of nanocrystal growth kinetics and nanoparticle surface properties.

TL;DR: In this article, a polyurethane sponge-supported titanium phosphate with graphene oxide, abbreviated as GO@TiP-Sponge, was characterized by X-ray diffraction, scanning electron microscope, energy-dispersive Xray spectroscopy and Xray photoelectron spectrography, and tested for the removal and recovery of trace dysprosium Dy(III), a rare earth element, in water using batch experiments.

TL;DR: In this article, a novel strategy for NaCl recovery and organic pollutants removal from the salt waste containing pyridine derivatives was developed by using acetone in salt waste solution, and the results showed NaCl was effectively recovered (recovery rate, 99.12%), and the TOC value of its saturated solution was reduced from 806.2 to 145.4.

TL;DR: In this article, a method for recycling waste gypsum by using a crystal phase regulation method was presented, where the waste was stirred and mixed with water to obtain a slurry, then an acid was added, the full stirring and uniform mixing was carried out to obtain the mixed slurry and then the obtained mixed silt was subjected to a hydrothermal reaction at a temperature of 50-250 DEG C for 1-24 h.
