“…So Nano ZnO at 700 O C corrosion inhibitor has the highest corrosion resistance compared to the other corrosion inhibitors used. Also, it is clear that as the temperature increases, the inhibition effect of the coating increases in agreement with [36][37][38] where the Icorr value decrement means the inhibitor concentration increment. The decrease in I corr value indicates that decrease in flow of electrons, i.e., corrosion is supressed on the specimen.…”

Three corroded mediums that found in the crude oil have been applied to carbon steel specimens. The effect of the corrosion mediums concentration, application periods and times investigated. The Gravimetric method showed that sodium thio sulfate has the highest corrosion effect at all corrosion test parameters followed by sodium sulfate and sodium carbonate respectively. Each of Nano zinc oxide, Nano cotton cellulose and Nano banana cellulose protective films inhibit sodium thio sulfate corrosion effect. Anti-corrosion behaviour of the formed Nano films studied using gravimetric method (weight loss method), electrochemical method (potentiodynamic polarization) and scanning electron microscope (SEM) techniques. The Nano zinc oxide heated at 700°C shown to have better inhibition efficiency followed by Nano zinc oxide heated at 600 OC, Nano cotton cellulose and Nano banana cellulose respectively. The potentiodynamic polarization measurements showed Nano zinc oxide heated at 700°C, Nano cotton cellulose, and Nano banana cellulose the acted as mixed-type inhibitors with predominantly cathodic effectiveness. SEM techniques supported the achievement of corrosion inhibition with the presence of inhibitors.

“…The use of carbon black in adsorbing dyes from wastewater has been reported and it was shown that poly(vinyl alcohol) coated carbon black has the ability to remedy water with considerable dye concentrations [10]. The same study also revealed that the kinetics of adsorption best fit the Langmuir and Freundlich isotherms.…”

The efficiency of using a composite of carbon black and sodium bentonite in treating drinking water contaminated with lead and copper ions was analyzed. The effects of pH, contact time, concentration and adsorbent dosage using an adsorbent composite of 20 % sodium bentonite and 80 % carbon black were studied. The adsorption data was analyzed with respect to Langmuir, Freundlich and Temkin isotherms. The data fits well with the Langmuir isotherm model with high coefficients of determination for both metal ions adsorption. The adsorption kinetics follows a pseudo second-order model for both metal ions. The maximum metal ion uptake (qmax) of composite adsorbent is 7.69 and 0.80 mg/g for lead and copper, respectively.

“…Adsorption is one of the most effective physical processes for the removal of textile effluents [11]. Many adsorbing materials have been tested to lower the dye concentration from aqueous solutions, such as activated carbon, rice husk, silica, chitin, fly ash, saw dust, bagasse pith, and orange peel [12]. Application of natural adsorbents has received much attention for the adsorption of various pollutants from aqueous medium.…”

The textile effluents are considered as potential source of water contaminations. Thus the effective methods were adopted for the removal of dyes and colorants from the textile effluents. In the present research, the removal of textile dye Congo red was carried out by bentonite clay blend with kaolin. The kaolin-bentonite clay (KBC) was used as adsorbent. The adsorption properties of KBC towards Congo red were investigated, at various temperatures 303-318 ±2 K under the optimized conditions. The adsorption equilibrium data were fitted in Langmuir, Freundlich and Dubinin-Radushkevich adsorption isotherm models and the values of the respective constants were evaluated by employing standard graphical method. From the graph, it was founded that Langmuir model is the best fitted isotherm. Feasibility of adsorption process (RL) and sorption energy (Es) was also determined. The pH of adsorbent was estimated by pH drift method. Kinetics of dye removal was investigated that it follows pseudo second order rate constant. The surface morphology of adsorbent was observed by the Scanning Electron Microscope (SEM).
