“…Equation representing Temkin and the D–R adsorption isotherm assumes that the heat of molecules adsorption in the phase decreases linearly when the layer is covered and adsorption has a uniform bond maximum energy distribution. The linear form of isotherms can be represented by q e (4)–(7), respectively:

“…The removal capacity ( q e , mg g −1 ) and efficiency ( η ) were calculated by the following equations:

q_{normale} = \frac{(C_{0} - C_{normalt}) V}{W}

η (%) = \frac{((), C_{0} - C_{t})}{C_{0}} \times 100 %

where C 0 and C t are the Cd(II) concentrations (mg L −1 ) at the initial time (zero) and time t , respectively; V denotes the solution volume (L); and W is the mass of the adsorbent (g) …”

Highly toxic divalent cadmium causes serious environmental issues. To quickly monitor and/or efficiently remove this potentially toxic metal ion as well as to explore its interfacial chemistry with metal oxides, a sulfur and carbon co-doped titania (S/C-TiO 2 ) composite is synthesized via a facile sol-gel method with the assistance of sodium lignosulphonate (SLS). The prepared composite displays a well-crystallized TiO 2 nanostructure comprising the anatase phase. Both S and C, which are derived from the SLS template, are found to enter the TiO 2 lattice. The S/C-TiO 2 composite exhibits a porous structure with a wide pore size distribution. The newly synthesized composite shows adsorption capability for the potentially toxic metal Cd(II). The adsorption process requires <5 min to reach equilibrium. The measured equilibrium adsorption capacity is 19.42 mg g −1 , which is twice as high as that of bare TiO 2 . The removal efficiency is as high as 97%. Moreover, the materials are suitable for contaminated solutions over a wide range of pH values and various initial cadmium concentrations. A mechanism for the enhanced adsorption behavior is also proposed.

This paper focuses on the development of an effective methodology to obtain the optimum ultrasonic‐assisted removal of a dye, safranin O (SO), under optimum conditions that maximize the removal percentage, using ZnO nanorod‐loaded activated carbon (ZnO‐NRs‐AC) in aqueous solution. Central composite design coupled with genetic algorithm was used for parameter optimization. The effects of variables such as pH, initial dye concentration, mass of ZnO‐NRs‐AC and sonication time were studied. The interactive and main effects of these variables were evaluated using analysis of variance. The structural and physicochemical properties of the ZnO‐NRs‐AC adsorbent were investigated using field emission scanning electron microscopy and X‐ray diffraction. Adsorption equilibrium data were fitted well with the Langmuir isotherm and the maximum monolayer capacity was found to be 32.06 mg g−1. Studies of the adsorption kinetics of the SO dye showed a rapid sorption dynamic with a pseudo‐second‐order kinetic model, suggesting a chemisorption mechanism.
