TL;DR: In this paper, UF membranes were prepared in outside skin tubular configuration using polysulfone and sulfonated poly sulfone polymers in order to study the effect of chemical nature of membrane surface on separation performance as well as surface fouling.

TL;DR: In this article, both reverse osmosis and forward Osmosis (FO) experiments are conducted to concentrate simulated inactive ammonium diuranate (ADU) filtered effluent solution (by mixing uranyl nitrate and ammonium nitrate) using indigenously developed cellulose acetate blend (CAB) and thin-film composite polyamide (TFCP) membranes.

TL;DR: In this article, a poly-acryl hydroxamic acid (PHOA) was used as an extractant for the recovery of uranium from nuclear waste solution, and various parameters such as sorbent solubility in different medium, effect of various cations on UVI sorption, desorption performance of different eluents with respect to U(VI) sorption has been investigated in detail.

TL;DR: In this paper, inorganic-organic composite (hybrid) sorbent was prepared from a radical initiated solution polymerization of acrylamide and freshly prepared titanium dioxide to minimize the inorganic sorbent (TiO2) loss.

TL;DR: In this paper, the pore-size distribution of the membrane and the molecular weight distribution of a complexing ligand were incorporated into the irreversible thermodynamic model by modifying the coefficients σ and ω to predict the rejection behavior of trace elements.
