“…Pollution caused by industrial wastewaters has become a threatening problem for many countries. The search for efficient wastewater treatment technologies has been intensified due to a growing public concern about health and related environmental issues of trace levels of pollutants [1][2][3]. Phenolic compounds are a group of the major and most undesirable pollutants present in wastewaters discharged by pharmaceutical, pesticides, oil, textiles, painting, dyes, plastic and detergent industries [4][5][6][7].…”

A new hybrid process that integrates adsorption on sawdust and electrochemical oxidation on a boron doped diamond anode was investigated for the treatment of dilute solutions containing phenol. In such combined process the pollutant is adsorbed until saturation and electrochemical oxidation has been used for both the regeneration of adsorbant and the pollutant removal. Phenol is used as model of pollutant and the efficiency of the regeneration of loaded sawdust has been compared with that of activated carbon (AC), a widely used adsorbent due to its high adsorption capacity which results from its high porosity. The study highlights the effect of electrolysis in the increase of the phenol desorption during the treatment of adsorbents. The regeneration efficiency of AC after 1 cycle of adsorption and regeneration is only 59% due to the electropolymerisation of the strongly adsorbed phenol. By contrast, the electrochemical regeneration of sawdust led to increase the adsorption capacity multiple adsorption and electrochemical regeneration cycles led to an enhancement of adsorption capacity of the sawdust with a complete removal of phenol and the possible reuse of the electrolysis solution.

“…In recent years, the improvement in electrochemical techniques has made these techniques used in the field of pharmaceutical, environmental and biological sample analysis predominantly because of their high sensitivity, low instrumentation cost with relatively shorter analysis time and removal of tedious extraction procedures, as compared with other analytical techniques [1] . Electrochemical techniques have been proven to be advantageous for developing very sensitive and selective methods for the determination of pharmaceutical, organic molecules and metal ions in samples of diverse origin [2] .…”

An electrochemically pretreated silver macroporous (Ag MP) multiwalled carbon nanotube modified glassy carbon electrode (PAN-Ag MP-MWCNT-GCE) was fabricated for the selective determination of an anti-hyperlipidimic drug, pitavastatin (PST). The fabricated electrochemical sensor was characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The fabricated electrode was employed in quantifying and determining PST through differential pulse adsorptive stripping voltammetry (DPAdSV) and CV. The electrode fabrication proceeded with remarkable sensitivity to the determination of PST. The effect of various optimized parameters such as pH, scan rate (ν), accumulation time (tacc), accumulation potential (Uacc) and loading volumes of Ag MP-MWCNT suspension were investigated to evaluate the performance of synthesized electrochemical sensor and to propose a simple, accurate, rapid and economical procedure for the quantification of PST in pharmaceutical formulations and biological fluids. A linear response of PST concentration in the range 2.0×10−7–1.6×10−6 M with low detection (LOD) and quantification (LOQ) limits of 9.66±0.04 nM and 32.25±0.07 nM, respectively, were obtained under these optimized conditions.

“…Thus, using a combined MEO/ 79 wet electrochemical scrubbing process using Ag II and Ce IV 80 catalysts, we investigated the removals of individual odorous 81 gases, such as, H 2 S, CH 3 SH, and NH 3[28][29][30]. In addition, we found 82 an activated Co III -MEO process suitable for the removal these gases 83 at low temperatures ($10 8C), which would make the process…”
