Chromium tanned leather wastes (CTLW) and vegetable tanned leather wastes (VTLW) were used as adsorbent materials to remove the Biebrich scarlet dye (BS), as an anionic dye from wastewater, using an adsorption method. The effects of various factors, such as weight of leather waste, time of shaking, and the starting concentration of Biebrich scarlet dye, temperature and pH were studied. It described the adsorption process using Langmuir and Freundlich isotherm models. The obtained results agreed well with the Langmuir model, and the maximum adsorption capacities of CTLW and VTLW were 73.5294 and 78.1250 mg.g⁻¹, respectively, suggesting a monolayer adsorption process. The adsorption kinetic was found to follow a pseudo-second-order kinetic model with correlation coefficients R2 > 0.9982 and 0.9900 for CTLW and VTLW, respectively. The results predicted that chromium leather wastes were more suitable adsorbents for the removal of BS dye from wastewater than vegetable tanned leather wastes, and the adsorption process is endothermic, according to the study of the effect of temperature.

“…There are many methods for degrading dyes in wastewater, including chemical, physical, and biological approaches, but most of these methods have high degradation and maintenance costs, and some produce secondary waste products that require further treatment, so they are not suitable or cost-effective for wastewater treatment (Garg et al 2015). Adsorption is a well-known separation process that can be used to decontaminate water (AbdulRazak et al 2018a). This process has been proven to be superior to other techniques for water reuse due to its low initial cost, simplicity and exibility of design, sensitivity to harmful pollutants, ease of operation, and because it does not lead to the creation of any hazardous Recently, several methods have been investigated for the production of less expensive and effective adsorbents.…”

In this paper, extract of Citrus aurantium (CA) was used as a green approach for the preparation of Fe3O4 nanoparticles. The green Fe3O4 (Fe3O4/CA) was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy analysis (EDX), Fourier-transform infrared (FTIR) spectroscopy, Brunauer–Emmett–Teller (BET) surface area measurement, vibrating sample magnetometry (VSM), and zeta potential (ZP) measurements. The synthesized Fe3O4/CA was used to remove methylene blue (MB) dye from an aqueous solution. A four-factor central composite design (CCD) combined with response surface modeling (RSM) was used to maximize the MB dye removal. The four independent variables, which were initial dye concentration (10-50 mg/L), solution pH (3-9), adsorbent dose (ranging from 200-1000 mg/L), and contact time (30-90 min), served as inputs to the model of the % dye removal. The findings yielded by an analysis of variance (ANOVA) confirmed the high significance of the regression model. The predicted values of the MB dye removal were in good agreement with the corresponding experimental values. Optimized conditions for the maximum MB dye removal (93.14%) by Fe3O4/CA were the initial dye concentration (10.02 mg/L), pH (8.98), adsorbent mass (997.99 mg/L), and contact time (43.71 min). The validity of the quadratic model was examined, and good agreement was found between the experimental and predicted values. Our findings demonstrated that green Fe3O4 NPs can be used as an adsorbent for MB dye removal.

“…When the values of (R) are higher than 0.8 this indicates there is good interaction between the response (droplet size and stability) and the independent parameters [18]. The values of the coefficients of determination are close to one, this refers to a good fit of the models with the experimental data and both models are significant, where the difference between the Adj Rsquared and the Pred-R squared less than 0.2 [19]. The values of R for two models are shown in Table V.…”

Nano emulsions (NEs) have important prospective advantages for assured industrials applications especially Metalworking fluids (MWFs), due to their Nano size, stability, than other types of traditional emulsions. In this work paraffin oil, water and mixture of surfactants Span20 & Tween20 are utilized for preparation of the MWF. A quadratic model was developed by applying the response surface method (RSM) to relate the droplets size and emulsion stability as a response to five independent variables namely the speed and time of mixing, concentration of the surfactant, Hydrophilic-Lipophilic Balance (HLB) value and pH value. Analysis of variance (ANOVA) was conducted; the results confirm the high significance of the regression model. The predicted values were found to be satisfactory with that experimental value. Mixing speed exerted the highest effect on the droplet size and the stability of the emulsion. The optimum conditions were found be (the concentration = 4.75 wt.%, time of mixing = 18.12 min, speed of mixing 14998.93 rpm, pH = 10.01 and HLB = 10.87) to attained Nano emulsion with 2 nm in size and stability of 24 days. Tool wear and surface roughness were studied at different speed, the results have showed that the wear ratio of the bits for all selected speeds is as follow: using commercial fluid > MWFs. The metallurgical microscope images have showed that, in case using MWFs the surface of cracks between the metals and the tool is more smooth compare with other fluids
