Adsorption of Na-Dodecylbenzenesulfonate onto Vinylon Fiber

Adsorption Onto Na-Mordenite

In the present study, the adsorption behaviors of mordenite (a common zeolite) with respect to Cu 2+ and Ni 2+ from aqueous solutions were investigated. The sorption data followed the Freundlich and Langmuir isotherms. The maximum sorption capacities were found to be 9.778 and 5.371 mg/g at pH 6, initial concentration of 40 mg/L and temperature of 30 for Cu 2+ and Ni 2+ , respectively. The kine...

Adsorption of Basic Blue 41 from Aqueous Solution onto Coconut Fiber Particles

In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...

adsorption of basic blue 41 from aqueous solution onto coconut fiber particles

Blood protein adsorption onto chitosan.

Chitosan was recently indicated to enhance osteogenesis, improve wound healing but to activate the coagulation and the complement systems. In the present study approximately 10 nm thick chitosan film were prepared on aminopropyltriethoxysilane (APTES) coated silicon. The surfaces were incubated in serum or plasma and subsequently in antibodies towards key complement and contact activation of co...

Adsorption of 5.5’-Disulfonicindigotin (5.5’-DI) onto Green Coconut Fiber (Cocos nucifera L.): Kinetic and Isotherms

Green coconut fiber (Cocos nucifera L.) has been largely used in solid-phase extraction. The effect of the initial dye concentration (1.91, 3.02 and 4.02) × 10−5 mol∙L−1 and solid phase contact (SPE) time were evaluated at different temperatures (283, 298 and 313) K at pH 2. Kinetic experimental data were applied to three simplified kinetic models: pseudo-first order, pseudo-second order, and i...
