Simultaneous elimination of diethyl phthalate, butylated hydroxy toluene and butylated hydroxy anisole from aqueous medium by an adsorption process on pretreated waste material; investigation of isotherms and neural network modeling

Combination of a dispersive solid phase extraction method based on octadecylamine modified magnetic nanoparticles with dispersive liquid–liquid microextraction for the extraction and preconcentration of pesticides

“…The absorption peaks at 2847 and 2916 cm À1 are assigned to C-H vibrations of aliphatic alkane. 34,35 Magnetic properties of the sorbent were evaluated by VSM analysis. The S-like magnetization hysteresis loop (Fig.…”

NiGA MOF-based dispersive micro solid phase extraction coupled to temperature-assisted evaporation using low boiling point solvents for the extraction and preconcentration of butylated hydroxytoluene and some phthalate and adipate esters

“…17 According to the health-threatening effects of the compounds of interest, they should be monitored in foods and beverages stored in plastic containers. Up to now, highperformance liquid chromatography 18 and gas chromatography (GC) 19 have been used for monitoring BHT, and phthalate and adipate esters. Since direct analysis is rarely possible using GC or results in high limits of detection (LODs) and quantication (LOQs) and also suffers from the matrix effect of the real samples, sample preparation procedures are inevitably necessary to be applied on samples prior to their injection into analytical apparatuses.…”

Ficus religiosa bark an efficient adsorbent for Alizarin Red S dye: Equilibrium and kinetic analysis

“…One of the most important areas of the research involving water pollution control is the removal of dyes from industrial effluents. A variety of treatment techniques including filtration [17], ion-exchange [18], coagulation/flocculation [19], electrolysis [20], reverse osmosis [21], waste water treatment by non-noble metal/reduced graphene oxide nanocomposite coated on wood and wood-based double-layer photo-absorbers [22][23], wastewater treatment by advance oxidation processes [24], adsorption are used for discoloring of wastewater [25][26][27]. Most of these processes are not cost-effective.…”
