“…In many cases the pseudo-first order model failed to describe the adsorption kinetic data Gupta 2006, 2011;Akar et al 2009;Chen and Zhao 2009;Koswojo et al 2010;Kurniawan et al 2011;Toor and Jin 2012;Vanamudan et al 2014;Wang et al 2014;Dos Santos et al 2015). Kurniawan et al (2011) found the inconsistency of the fitted value of parameter k 1 with its physical meaning, the value of k 1 , increase with the increasing of initial solute concentration, hence the pseudo-first order model is not the correct choice to represent the kinetic experimental data.…”

“…In most adsorption systems using clay minerals and its modified forms as the adsorbents, the pseudo-second order kinetic model could represent the experimental data much better than the pseudo-first order kinetic Gupta 2006, 2011;Tsai et al 2007;Akar et al 2009;Chen and Zhao 2009;Koswojo et al 2010;Kul and Koyuncu 2010;Kurniawan et al 2011;Toor and Jin 2012;Auta and Hameed 2012;Lv et al 2014;Vanamudan et al 2014;Wang et al 2014;Dos Santos et al 2015). A potential advantage of the pseudo-second order equation as an expression estimating the q e values is its small sensitivity to the influence of the random experimental error (Plazinzki et al 2009).…”

“…The intra particle diffusion model could represent the adsorption kinetic data quite well for several systems such as congo red-nano clay filled composite hydrogels and methyl violet-nano clay filled composite hydrogels (Bhattacharyya and Ray 2015), Basic yellow 28-amidated pectin/montmorillonite composite (Nesic et al 2014), Rhodamine 6G-chitosan-g-(N-vinyl pyrrolidone)/montmorillonite composite (Vanamudan et al 2014), Cobalt(II)-chitosan-montmorillonite (Wang et al 2014), Indigo carmine-CdSe montmorillonite composite (Chikate and Kadu 2014), picloram herbicide-montmorillonite (Marco-Brown et al 2014), phenol and cathecol-gemini surfactant modified montmorillonite …”

For the design of the adsorption system, reliable adsorption kinetic data are required. Different concepts are employed to develop a reliable adsorption kinetic model. Most of the available models were developed according to mass transfer principles or the concept of chemical reaction occurring on the surface of a solid. The models based on the surface-reaction kinetic step as controlling the sorption rate have also been proposed, these models include pseudo-first order kinetic (also called as Lagergren model), pseudo-second order kinetic, and Elovich equation. This chapter discusses various aspects of pseudo-first order kinetic and pseudo-second order kinetic in representing the adsorption kinetic data of some hazardous compounds onto clay minerals. The pseudo-first order kinetic is the earliest known equation to describe the rate of sorption in the liquid phase system. The behavior of time constant parameters k 1 and k 2 of pseudo-first order kinetics and pseudo-second order kinetics as a function of initial concentration as well as the temperature is discussed in this chapter. One of the kinetic models which also widely used to represent the sorption kinetic data is an intraparticle diffusion model also briefly discussed in this chapter.Keywords Adsorption kinetic · Pseudo-first · Pseudo-second · Intraparticle diffusion Adsorption kinetics are expressed as the solute removal rate that controls the residence time of the solute in the solid-solution interface. Reliable sorption kinetic data are of substantial value for adsorption separation system design. Various models have been developed to adequately describe the kinetics of sorption of the solid-liquid system. However, due to its complexity compared to the description of adsorption equilibria, the progress of development of various sorption kinetics appears to be limited. In general, the adsorption of solute from aqueous solution

“…Hence, bentonite can be used as fillers in various polymer matrices to prepare nanocomposites because the functional groups of bentonite such as SiAOASi can interact strongly with functional groups in polymer matrices such as AOH, ANH 2 , ACOOH and N-acetyl glucosamine units (Darder et al 2005). A different composite with chitosan has been done by several researchers (Vanamudan et al 2014;Abdel Khalek et al 2012;Thayyath Sreenivasan Anirudhan et al 2010).…”

In the present era, due to industrial revolution in the developing countries like India, the ground water system has been largely polluted. Tannery effluent is a major source of aquatic pollution, and a large number of tanneries are scattered all over India particularly in Tamilnadu, Uttar Pradesh and West Bengal. This work deals with the removal of heavy metals chromium and lead and the reduction of the important physicochemical parameters like total dissolved solid (TDS), total suspended solid (TSS), total solids (TS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total hardness, salinity, turbidity and electrical conductivity from the tannery wastewater by using chitosan-g-poly(butyl acrylate)/bentonite nanocomposite as an adsorbent. The batch system was used to conduct the biosorption experiments. The influence of different experimental parameters, such as contact time, pH and amount of adsorbent, was evaluated. The results showed that the prepared nanocomposite can be used efficiently for the treatment of tannery wastewater containing heavy metals.

“…Due to its non-toxicity, eco-friendliness, high availability, low cost and good adsorption properties, chitosanbased materials have been increasingly used as biosorbents for pollutants removal from wastewaters, such as dyes [10], fluoride [11], Cr(VI) [12], Hg(II) [13], Cu(II) [14], Pb(II), Cd(II) and Ni(II) [15], As(III) [16] and others [17,18]. Besides, the incorporation of electropositive metal with chitosan can enhance the selectivity and adsorptive properties of the biosorbent for those above contaminants.…”
