Adsorption is the most versatile and widely used method for the removal of pollutants due to its high efficiency and ease of operation at large scale. In recent years nano metal oxides have been extensively used for the removal of pharmaceutical pollutants from waste water. In the present study, the adsorption behaviour of ciprofloxacin hydrochloride from aqueous medium, using CuO nanoparticles...

The role of micropore size and N-doping in CO2 capture by microporous carbons has been investigated by analyzing the CO2 adsorption properties of two types of activated carbons with analogous textural properties: (a) N-free carbon microspheres and (b) N-doped carbon microspheres. Both materials exhibit a porosity made up exclusively of micropores ranging in size between <0.6 nm in the case of t...

The recent letter to the editor by Bickford et al. [1] discusses the uses of the CO2 affinity coefficient in microporous carbons, bCO2 , and its physical significance. The paper points out the lack of having absolute b values and attempts to give answer to the question of the suitability of the value of bCO2 = 0.35 in microporous carbons. The authors conclude that this cannot be considered a ‘‘...

This study aimed to evaluate the methyl red (MR) removal efficiency from aqueous matrices using an eco-friendly anionic surfactant (a calcium surfactant, or CaSF), obtained frying oil residue. Data by infrared spectroscopy revealed several functional groups that favor capture of dye chemisorption forming hydrogen bonds and covalent interactions. The kinetic testing results fit pseudo-second ord...

The objective of this study was to assess the adsorption potential of activated carbon (AC) asan adsorbent for the removal of Murexide (Mu) from aqueous solutions. The influence of variablesparameters including pH, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon Mu removal was studied. Following optimization of variables, the relation between concentrations ofdye re...

This study aimed to evaluate the adsorption capacity of an adsorbent obtained using sanky peel for removal phosphate from aqueous solutions. The was conducted in two stages: (1) preparation considering yield, removal, capacity, and textural characteristics; (2) assessment effectiveness as removing phosphates Batch studied solutions containing calcium ions with selected adsorbent. Adsorption kin...

Production of biochar is accomplished by pyrolysis corncobs at 350 °C (BC-350) and 450 (BC-450) under oxygen-limited conditions. The chemical physical properties were investigated via XRD, FTIR, BET, SEM EDX analysis. Batch experiments conducted for the adsorption Pb2+ ions from aqueous solution onto with regards to pH, contact time, dose initial concentration. efficiency was increased as incre...

Environmentally, removing organic pollutants from industrial waste solutions is important. In this study, the potentiality of Thoron (TH) and Arsenazo III (ARZIII) was investigated using chemically stable zinc tungstate nanoparticles (ZW-NPs). The preparation ZW-NPs performed an eco-friendly solvo/hydrothermal technique as a sorbent. Complete characterisation before after adsorption processes X...
