Modeling synergistic adsorption of phenol/aniline mixtures in the aqueous phase onto porous polymer adsorbents

Kinetics and thermodynamic study of aniline adsorption by multi-walled carbon nanotubes from aqueous solution

“…Short multi-walled carbon nanotubes with average diameters of 10-20 nm [SMWCNTs (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)] and short multi-walled carbon nanotubes with average diameters of 40-60 nm [SMWCNTs (40-60)] were obtained from Shenzhen Nano-Technologies, China (MWCNTs Shenzhen) and were used as received. All chemicals used in this study were obtained from Sigma-Aldrich (analytical grade), and all solutions were prepared using deionized water.…”

“…1. The outer diameters and inner cavities of MWCNTs (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) were 20-30 nm and 5-8 nm, respectively. The outer diameters and inner cavities of SMWCNTs (40-60) were 30-70 nm and 8-12 nm, respectively.…”

“…In addition, the TEM analysis verified the hollow structure of the MWCNTs. Nitrogen adsorption/desorption isotherms for the pristine SMWCNTs (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) and SMWCNTs (40-60) were determined from a N 2 adsorption isotherm measured at 77 K; the results are presented in Fig. 2.…”

“…Traditionally, aniline-containing wastewater is treated with photodecomposition [1][2][3], electrolysis [4], adsorption [5,6], oxidation [7,8], biodegradation [9] and other processes. Generally, adsorption technology has proved to be one of the most effective techniques in the separation and removal of a wide variety of organic pollutants from wastewater [10,11]. These techniques do not produce harmful byproducts, and the regeneration of both the adsorbent and pollutants is possible.…”

Assessment on the removal of dimethyl phthalate from aqueous phase using a hydrophilic hyper-cross-linked polymer resin NDA-702

“…However, Amberlite XAD-4 resin has a hydrophobic surface and a lower adsorption capacity for most organic substances compared with activated carbon, which limits its wide application in the treatment of contaminated water [15]. Recently, some chemically modified polymeric resins have been synthesized and applied in organic pollution control for industrial waste streams in our previous studies [16,17]. Nevertheless, less work focusing on the removal of phthalates using polymer resins was reported [18].…”
