Abstract: In this work, the carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) were chemically modified with 3-aminopyrazole to synthesize MWCNTs-f. Then the three nanoadsorbents, i.e., MWCNTs, MWCNTs-COOH, and MWCNTs-f, have been separately used to the adsorption of Cd(II) ions from aqueous solutions. The adsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDS), field emission scanning electron Microscope (FE-SEM), thermal gravimetric analysis (TGA), and Bruner-Emmet-Teller (BET) surface area measurement. The effects of pH, adsorbent dose, initial ion concentration, and temperature on adsorption efficiency were investigated by central composite design a subset of response surface methodology for experimental design to reducing the number of experiments runs having the interaction effects between the parameters. The optimum adsorption conditions for all adsorbents were 20 mg of the adsorbents, pH = 8–9, and 50 mg L −1 of Cd(II) ions at 45 °C. At the optimum conditions, Cd(II) ions removal efficiencies were 83.7, 65.9 and 35.7% for MWCNTs-f, MWCNTs-COOH, and MWCNTs, respectively. The quadratic model was applied for analysis of variance and indicated that pH and temperature were the most effective parameters in the adsorption process. The pseudo-second-order model was achieved from the adsorption kinetic studies. Also, various adsorption isotherm models at different temperatures were examined. The results show that the Langmuir isotherm is fitted suitably for the three adsorbents in this work and the best-selected isotherm models for the adsorption of Cd(II) ions by MWCNTs, MWCNTs-COOH, and MWCNTs-f were Langmuir, Dubinin–Radushkevich and Temkin models, respectively. Moreover, desorption study revealed the favorable regeneration ability of adsorbents powders, even after 3 adsorption-desorption cycles.

Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural and industrial waste materials. Use of waste materials as low-cost adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. This e-book explores knowledge on recent developments in adsorbents synthesis and their use in water pollution control. This handy reference work is intended for researchers and scientists actively engaged in the study of adsorption and the development and application of efficient adsorption technology for water treatment. This e-book covers a wide range of topics including modeling aspects of adsorption process and the applications of conventional and non-conventional adsorbents in water remediation emphasizing sorption mechanisms of different pollutants on the adsorbents.
