Glucomannan/graphene oxide (GM/GO) hydrogel was synthesized by using calcium hydroxide as the crosslinker. The synthesized material was characterized by using IR, XRD, SEM, EDX and RAMAN technology. The composite hydrogel was used for removal of organic dyes from aqueous solution. The results showed that the GM/GO hydrogel had a porous structure and a high adsorption capacity toward methylene blue (MB). The pseudo-second-order kinetic model could fit the rate equation of MB adsorption onto the GM/GO hydrogel. The adsorption of MB onto GM/GO hydrogel was a spontaneous process. In addition, the equilibrium adsorption isotherm data indicated that equilibrium data were fitted to the Langmuir isotherm and the maximum dye adsorption capacity was 198,69 mg.g-1. Moreover, the hydrogel was stable and easily recovered and adsorption capacity was around 97% of the initial saturation adsorption capacity after being used five times.

<span lang="EN-US">Electrocoagulation (EC) was used for the removal of anthraquinone dye, Alizarin Red S (ARS) from aqueous solution, the process was carried out in a batch electrochemical cell with Al electrodes in monopolar connection. The effects of some important parameters such as current density, pH, temperature and initial dye concentration, on the process were investigated. Equilibrium was attained after 10 minutes at 30 oC. Pseudo-first-order, pseudo-second-order, Elovic, and Avrami kinetic models were used to test the experimental data in order to elucidate the kinetic of the electrocoagulation process; pseudo-first-order and Avrami models best fitted the data. Experimental data were analyzed using six isotherm models: Langmuir, Freudlinch, Redlich–Peterson, Temkin, Dubinin–Radushkevich and Sips isotherms and it was found that the data fitted well with Dubinin–Radushkevich and Sips isotherm model. The study showed that the process depend on current density, temperature, pH and initial dye concentration. The calculated thermodynamics parameters (∆G<sup>o</sup>, ∆H<sup>o</sup> and ∆S<sup>o</sup>) indicated that the process is spontaneous and endothermic in nature.</span>

To improve the adsorption and separation efficiency of lead-containing wastewater by graphene oxide (GO), attapulgite (ATP) was used through a simple hydrothermal reaction. The prepared GO was characterized by SEM, TEM, FTIR, and XPS. The adsorption properties of the prepared GO were investigated. The maximum adsorption capacity of Pb2+ on as-prepared GO at pH 5 and 25 °C was 450.9 mg/g. It is concluded that the as-prepared GO can be used as a high-efficiency adsorbent for lead-containing wastewater.

p-Phenylenediamine functionalized magnetic graphene oxide nanocomposites (PPD-MGO) were prepared and utilized in the adsorption and removal of bisphenol A in aqueous solution. The novel nanomaterials were characterized by transmission electron microscopy (TEM), Fourier infrared spectrometry (FT-IR) and vibrating sample magnetometer (VSM). The factors affected the adsorption of bisphenol A including adsorption time, temperature and pH of solution, adsorption kinetics and isotherms were all investigated. The results showed that PPD-MGO nanomaterial exhibited good adsorption ability for bisphenol A and good resuability. The maximum adsorption capacity reached 155.0 mg g-1 at 45?C and pH 7. The removal rate was 99.2 % after three times of adsorption with new nanomaterials. After five cycles adsorption, the adsorption capacity of PPD-MGO remained at 94.0 %. The adsorption of bisphenol A was found that fitted pseudo second order kinetics equations and the Freundlich adsorption model. The experimental results showed the PPD-MGO nanomaterial had a good adsorption ability to remove organic compounds in aqueous solution.
