Removal of Reactive Black 5 (RB5) dye from an aqueous solution was studied by its adsorption on banana peel biochars (BPBs). The factors affecting RB5 such as pH, exposure time, concentration, adsorbent dose, particle size and temperature were investigated. Maximum 97% removal obtained at pH 3 with 75 mg/L adsorbate concentration biochars. Fourier transform infrared (FTIR) scanning electron mic...

Many industries use huge amounts of synthetic dyes which may release into the wastewater in dyeing processes causing serious damage to aquatic life as they are recalcitrant, nonbiodegradable, stable oxidizing agents, and toxic. Adsorption on activated carbon has been found be a very efficient treatment method. In this work, new adsorbent material composed aluminum chloride (AC-Al) was prepared ...

In this work, the degradation performance of Fe2+/PAA/H2O2 on three typical pollutants (reactive black 5, ANL, and PVA) in textile wastewater was investigated comparison with Fe2+/H2O2. Therein, had a high removal RB5 (99%) mainly owing to contribution peroxyl radicals and/or Fe(IV). Fe2+/H2O2 showed relatively PVA (28%) resulting from ·OH. comparative removals ANL. Additionally, more sensitive...
