The prevalent problems associated with heavy metal contamination of the environment particularly underground and surface wastewater compel need to work on economical means mitigating accumulation metals in by espousing biosorption option. choice this regard is hinged overall cost control process its relative effective outcome compared other diminishing environment. Thus, potential Garden Egg (S...

The close link between the roughness of a surface and its adsorptive properties in Cerofolini’s model yields, with an adequate choice adsorption energy, well-known Dubinin-Radushkevich or Freundlich isotherms. Assuming fractal behavior concerning both energetic geometric heterogeneities described by power-law expressions dimensions, paper will develop some Using our theoretical approach, isothe...

Polyethersulfone-sulfonated polyethersulfone (PES-SPES)/NaY zeolite/nylon sandwich structure membranes were prepared and used to adsorb Cu2+ from water. The adsorption kinetics, isotherm, dynamic experiment, reusability discussed. experimental data showed that the Langmuir isotherm model, Dubinin–Radushkevich (D-R) pseudo-first-order kinetic model can well represent of on membrane, indicating a...

In our study a new Fe-modified nano porous of MCM-41 was synthezied hydrothermally with cetyltrimethylammoniumbromide (C16TAB) as surfactant and charactrizied using XRD, SEM, FT-IR and BET. This work reports the adsorption of Neodymium from aqueous solution onto Fe-MCM-41.100 ml of stock solution of Neodymium was prepared.Various factors such as pH,the amount of adsorbent were considered. T...

The Frumkin or Fowler–Guggenheim isotherm, which has three fitting parameters, is often converted to a linear form with two parameters facilitate parameter estimation by regression. This conversion made possible way of replacing the unknown capacity isotherm surrogate value. certain simple isotherms (e.g., Dubinin–Radushkevich) are used as surrogates. However, such surrogates have never been ev...

Black cumin seed pulp (C), as well biochar (CC) produced via pyrolysis of black were used to remove methylene violet 2B (MV) and basic yellow 28 (BY28) from aqueous solution. Adsorption isotherms kinetics applied at 10, 25, 35 °C. The adsorption on the surface was exothermic; heat values lower than 0. capacities BY28-C, BY28-CC, MV-C, MV-CC 212.8, 625, 164, 909 mg g-1 25 °C, respectively. data ...
