Removal of Diclofenac and Heavy Metal Ions from Aqueous Media Using Composite Sorbents in Dynamic Conditions.

Pharmaceuticals and heavy metals pose significant risks to human health and aquatic ecosystems, necessitating their removal from water and wastewater. A promising alternative for this purpose involves their removal by adsorption on composite sorbents prepared using a conventional layer-by-layer (LbL) method or an innovative coacervate direct deposition approach. In this study, four novel composite materials based on a silica core (IS) and a polyelectrolyte coacervate shell were used for the investigation of dynamic adsorption of three heavy metals (lead, nickel and cadmium) and an organic drug model (diclofenac sodium salt, DCF-Na).

Environmental monitoring and impact assessment of Prut River cross-border pollution.

The cross-border rivers management is a challenge for the involved countries, especially if they do not have the same type of legislation. The negative effects on water quality are quantified by using environmental impact assessment tools. Thus, the quantification of impacts that could affect the human health, ecosystem equilibrium, and biodiversity is based on monitoring of the water quality indicators.
