“…Carbon has porous structure which limit its adsorption capacity and as is known via its unique chemical structure able to interact with polar and nonpolar adsorbates. It has active sites in the form of edges, dislocations and discontinuities which determine its chemical reactions with other atoms, which guide that cooperating occur in addition to surface area and pore size distribution . Activated carbons supply equal surface area which prepared from different methods and/or surface and also different activation treatments proses various structure and accordingly adsorption properties .…”

The simultaneous and competitive ultrasound‐assisted removal of naphthol green B (NG‐B) and phenol red (PH‐R) dye from aqueous solutions were rapidly performed onto copper‐doped zinc sulfide nanoparticles loaded on pistachio‐nut shell activated carbon (Zn‐S: Cu‐NPs‐PAC). Novel adsorbent was recognized by FT‐IR, EDX, SEM and particle size distribution techniques. First, the effect of pH on the removal efficiency was optimized by one‐at‐a‐time procedure and subsequently dependency of dyes removal in their binary situation to variables such as sonication time, initial dyes concentrations and adsorbent dosage was fully investigated and optimized by central composite design (CCD) under response surface methodology (RSM) as well as by regarding desirability function (DF). The good agreement between experimental and predicted values supports suitability of the present model for well definition adsorption state. The ultrasound strongly enhanced mass transfer and performance, while 0.035 g of adsorbent is sufficient and capable to remove high percentage (>99.0%) of dyes in the rapid time (6 min). The experimental equilibrium data represented by Langmuir at mild conditions for successful removal of high adsorption capacity in binary system (196 mg g−1 for PH‐R, 76 mg g−1 for NG‐ B). Kinetics evaluation of experiments at various time intervals reveals applicability of pseudo‐second‐ order models for description of adsorption processes.

“…In general, photocatalytic degradation is one of the widely applied methods to treat aqueous dye contaminants. 19 However, to the best of my knowledge, after the photo-catalytic treatment, the photodegraded dye solution has never been tested for its corrosion behavior towards metal. In this context, we have explored a few important insights suggesting that the photodegraded dye solution is detrimental and capable of inducing corrosion of the aluminum metal substrate.…”

The corrosion protection performance of epoxy coatings could be enhanced by incorporation of nanofillers such as MWCNT. However, a homogeneous dispersion of MWCNT in epoxy polymer is still a teasing challenge. Herein, we report an environmentally benign single‐step supercritical CO2 processing method to improve the dispersion of MWCNT in epoxy matrix in order to achieve an effective anticorrosive coating. The executed approach provides a cluster‐free uniform distribution of MWCNT in epoxy matrix as characterized with UV‐visible spectroscopy, Fourier transforms infrared spectroscopy, X‐ray diffraction, and surface analysis. The anticorrosive characteristics of MWCNT/epoxy coating were studied in NaCl as well as in photodegraded dye medium through electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. We observed the remarkable corrosion of model metal substrate in photodegraded dye medium besides NaCl medium. In both mediums, the protection efficacy of MWCNT/epoxy coating was deduced from the stable impedance arcs in Nyquist plot and increased impedance modulus. The electrochemical impedance spectra were best fitted with equivalent circuits showing the higher values of pore resistance. Also, the MWCNT/epoxy coating exhibited a positive shift of corrosion potential and possessed a lower corrosion rate as compared with neat epoxy coating. More direct evidence of the excellent barrier properties for MWCNT/epoxy coating was visualized in SEM images. The obtained results implied that the superior dispersion of MWCNT into epoxy matrix significantly reduces the porosity of coating and inhibits the permeability of corrosive ions. We expect supercritical CO2 assisted dispersion method can offer an efficient, cost‐effective, and industrially viable route to develop high performance protective coatings for varied commercialized applications.
