An overview of chlorophenols as contaminants and their removal from wastewater by adsorption: A review
2019, Journal of Environmental ManagementCitation Excerpt :pH, as well as ionic strength, are among the key factors impacting the adsorption of phenolic compounds. In acidic solution, the uptake of phenolic compounds by different adsorbents is intensified because the phenols are undissociated (Caqueret et al., 2008; Dargaville et al., 1996; García-Araya et al., 2003; Grant and King, 1990; Mohan and Karthikeyan, 1997). On the other hand, adsorption decreases at higher pH due to the occurrence of hydroxyl and carboxyl groups dissociation (Fu et al., 2005; Yoon et al., 1997).
Adsorption of heavy metal ions from aqueous solutions by amine and carboxylate functionalised bentonites
2012, Applied Clay ScienceCitation Excerpt :The concentration of amine groups in BentNH2 was estimated using volumetric method (Zhu and Alexandratos, 2005). Boehm titration (Dargaville et al., 1996) was performed to determine the amount of carboxyl groups in BentCOOH. The FTIR spectra were obtained using a Nicolet Protege 460 spectrophotometer.
Recovery, concentration and purification of phenolic compounds by adsorption: A review
2011, Journal of Food EngineeringCitation Excerpt :The effect of oxygen on the adsorption of polyphenolics onto resins has been scarcely addressed (Saleh et al., 2008). Adsorption is also influenced by the adsorbate characteristics (Dargaville et al., 1996; Brune et al., 1999; Pan et al., 2005; Cheng et al., 2006; Li et al., 2009; Navarro et al., 2008a; Geng et al., 2009). Adsorption from a multicomponent solution is a complex problem (Kammerer et al., 2007; Kammerer et al., 2010a; Kammerer et al., 2010b; Silva et al., 2007).
Non-ionic surfactant interactions with hydrophobic nanoparticles: Impact on foam stability
2009, Colloids and Surfaces A: Physicochemical and Engineering AspectsCitation Excerpt :Hence, the structure is believed to be a close packed monolayer, with solution facing head-groups remaining exposed throughout adsorbed layer build-up, despite the clear evidence of inter-surfactant attraction in the isotherm. To better highlight this adsorption mechanism, and possible aggregation of surfactant at the interface, the Langmuir equation was used [49,54,60]. For a species adopting a Langmuir type monolayer, a linear relationship exists between the ratio of equilibrium surfactant concentration (Ceq) and adsorbed amount (Γ).
