A highly hydrophobic and oleophilic sponge was synthesized by simple vapor-phase deposition followed polymerization of polypyrrole modification with palmitic acid. The prepared shows high absorption capacity in the field separation removal different oil spills from water surface able to emulsify oil/water mixtures. can be compressed repeatedly without collapsing. Therefore, absorbed oils readily collected mechanical squeezing sponge. collect both static turbulent conditions. proposed method...
The kinetics of adsorption processes at the solid/solution interface has been studied by using a fractal-like concept. For first time, one possible physical meaning for which indicates that sorption rate coefficient is function time presented. So, new kinetic models have presented combination approach and integrated Langmuir equation (IKL), mixed 1,2-order (MOE), statistical theory (SRT). SRT solved two limiting conditions, initial times other close to equilibrium. parameter (α) appeared in...
In this study, sodium alginate was employed as a starting material for preparing two kinds of biocompatible adsorbents, including calcium hydrogel beads and magnetic beads. Fourier transform infrared spectroscopy, X-ray diffraction pattern, scanning electron microscopy/energy-dispersive techniques were used to characterize the prepared adsorbents. The performance adsorbents removal methyl violet from aqueous solution studied in detail. Both kinetics equilibrium aspects adsorption...
A physical meaning of the fractal-like concept has been represented for kinetics adsorption on energetically heterogeneous solid surfaces. This study shows that at solid/solution interface in a real system with different types surface sites and then affinity can be described by approach. On basis this study, history process affect rate process, therefore observed coefficient is function time. Employing to extend some kinetic models leads obtaining utilized simulate systems The simulation...
The effects of diffusion and surface reaction mechanisms have been considered conjointly to investigate the kinetics adsorption. A new model has proposed for modeling adsorption at solid/solution interface in batch systems. Based on generated data points (t, q) by using model, it was found that there is a deviation from linearity as downward curvature initial times usual t/q vs time plot, when contributes rate-controlling step Moreover, results nonlinear fitting different experimental show...
In chemical synthesis, obtaining product(s) with high purity is a crucial issue from both academic and industrial viewpoints. Higher of the means higher quality lower production costs. Sometimes, purification separation processes are very laborious lead to significant impacts on final price desired product(s). Simple new synthetic methods for preparation highly pure have always been challenge chemists. this paper, relationship between mass reactants, quantity amount each substance, number...
Interfacial solar evaporator generation (ISVG) is a new, cost-effective, and eco-friendly emerging method for water desalination. Two main criteria evaluating ISVG performance are evaporation rate (ṁ) solar-to-vapor conversion efficiency (η). The challenge of the previously presented models estimation ṁ η in 2D systems that most cases calculated values beyond theoretical limits, > 1.47 kg m–2 h–1 100%, both which not acceptable from thermodynamics viewpoint. Also, recently strategy reduced...
