TL;DR: The main trend observed in the variation of the arsenic sorbed with pH is the decrease of the sorption on the three sorbents at alkaline pH values, which agrees with results found in the literature.

TL;DR: This work study the interaction of Se(IV), and Se(VI) with natural iron oxides hematite and goethite through two series of batch experiments at room temperature using a triple layer surface complexation model and using the FITEQL program.

TL;DR: The results showed that the lower the content of lignin in the organic substrate, the higher its biodegradability and capacity for developing bacterial activity.

TL;DR: The stabilization of metals was successful in all cases, although the immobilizing system shows a better behaviour for Pb(II) and Cr(III) under acidic or neutral conditions.

TL;DR: In this article, a general rate equation has been derived: r= k 1 k 2 { >UO 2 } tot [ O 2 ][HCO 3 − ] k −1 +k 2 [ HCO3 − ]+k 1 [O 2 ], which allows to rationalization some of the discrepancies found in the literature concerning the dependence of the dissolution rate of uranium dioxide on the hydrogen carbonate concentration.
