Carbonaceous materials are a highly appealing class of adsorbents, owing to their exceptional properties, such as high surface area and thermal chemical stability. These have found successful applications in water purification. Sweet chestnut (Castanea sativa) cupules disposed waste. Valorization these residues is step forward terms circular economy sustainability. Meanwhile, per- poly-fluoroal...

Among the different photocatalysts, TiO 2 ( E g = 3.1 eV, zero charge point (pHpzc 6.3), and surface 55 m /g) is currently most efficient studied semiconductor due to its strong photocatalytic activity, non-toxicity, chemical stability. The elimination of DR-80 on by adsorption in batch mode application heterogeneous photocatalysis onto under UV irradiation. effects contact time (0–60 min), ini...

In this study, we evaluated the use of prickly pear seed cake, a by-product oil extraction, as new precursor for producing activated carbon by phosphoric acid activation, and obtained carbon’s capacity heavy metal removal from aqueous solution. Response surface methodology based on full factorial design at two levels (24) was developed to reduce number experiments reach optimal preparation cond...

Abstract This study contributes to the current state of knowledge by highlighting physical–chemical interactions between biochar and dyes. The removal Acid Orange 7 (AO7) dye a modified obtained from wastes mandarin peels (MPs) has been investigated in this work. A dehydration procedure with 80% H 2 SO 4 under reflux was applied produce an innovative MPs then boiled O followed boiling triethyle...

The structure of water at the (110) surface of cassiterite (alpha-SnO2) at ambient conditions was studied by means of molecular dynamics simulations and X-ray crystal truncation rod experiments and interpreted with the help of the revised MUSIC model of surface protonation. The interactions of the metal oxide in the simulations were described by a recently developed classical force field based ...

A new hydrogel beads-sponge structure (these beads combine the properties of with sponge character) a super rate swelling in water and wastewater large porosity was created during this research. New biosorbents were obtained by modification three parts Moringa oleifera (seeds, leaves husks). Prepared adsorbent characterised some analytical methods, viz. FT-IR, SEM SEM-EDX. The effects operation...

Aniline and its derivate are critical environmental pollutants, thus, the introduction of an eco-friendly catalyst for removing them is important research future. The ZnO supported on ball-mill prepared clinoptilolite nanoparticles (CNPs) was via ion-exchange process followed by calcination process. amount loaded in ZnO-CNP (CZ) samples varied as 0.54, 0.63, 0.72, 0.86 meq/g Zn(II) concentratio...
