“…Under acidic condition (pH<3.3) due to protonation, the cationic form of DCH (+00) develops the electrostatic repulsion with predominant cationic monomers of Al 3+ and Al(OH) 2+ and lessens the removal efficiency of DCH (Ouaissa et al 2014). The possibility of DCH speciation at various pH values (Zhang et al 2011) as zwitterion (±0) was due to the loss of proton from the phenolic diketone moiety.…”

Electrochemical treatment involving a coupled coagulation and floatation was performed in the removal of Doxycycline Hyclate (DCH) from aqueous solutions. All the experiments were carried out in an electrochemical reactor of 1.5 L which contained aluminium electrodes as cathode and anode. The removal of doxycycline hyclate (DCH) species by EC/EF was determined as a function of electrolysis time, pH, current intensity, flow rate and DCH concentration. From the observed results, it was corroborated that the DCH removal through the EC/EF process was excellent. The effective contribution from initial pH (7.03) and current intensity (5.39 mA cm -2 ) was very much remarkable and well apparent from flocs of good buoyancy. The removal of DCH was inversely proportional to spacing between electrodes (SBE) and circulating flow rate in the presence of the supporting NaCl electrolyte of 1 g L -1 . It was also highly promoted by the addition of NaCl in comparison to NaNO 3 and KCl to the electrolytic system. The compliance of four kinetic models was verified with DCH removal system. The free energy values from DKR model suggested the nature of bonding by chemical forces. Characterization by FTIR, SEM and XRD interpreted the assignments of various functional groups, surface morphology and crystalline incorporated amorphous nature, respectively of electro -generated flocs. The current efficiency and specific electrical energy consumption at optimized conditions of the EC/EF system were calculated.

In this work, nanoporous MCM-41 silicate was used for the Victoria blue adsorption and removal from the aqueous solutions. The properties of the synthesized MCM-41 were determined by X-ray diffraction analysis, transmission electron microscopy, and TGA analysis. The method is based on the adsorption of Victoria blue after passing on MCM-41 in a column. The adsorption with respect to contact time, pH, flow rate of sample, and initial concentration of analyte was investigated to provide more information about the adsorption characteristics of MCM-41. After adsorption of the dye, the concentrations of residual dye were determined by UV-Vis spectrophotometer. Adsorption process is well described by Langmuir and Temkin isotherms in comparison with Frundlich isotherm. Results suggested that the adsorption of Victoria blue on calcined MCM-41 was a spontaneous and endothermic process. The experimental data fitted very well with the pseudo-second-order kinetic model for Victoria blue onto calcined MCM-41. Adsorption capacity was found to be 192.3 mg g −1 . The method was applied to the adsorption and removal of Victoria blue in different environmental water samples.
