香菇下脚料对水体中十二烷基苯磺酸钠的吸附
Adsorption of sodium dodecylbenzenesulfonate from aqueous solutions by lentinus deodes residue
摘要
Abstract
The lentinus deodes residue (LDR) were prepared as an adsorbent by mixed solution of formaldehyde/sulphuric acid, and the adsorbent were investigated in relation to its adsorption behavior for sodium do-decylbenzenesulfonate( SDBS). The effects of solution pH , particle size, initial concentration, adsorption time, concentration and temperature were considered. It showed that pH of 4.0 and shaking time of 60 min were the optimal conditions for adsorption of SDBS. The adsorption process followed a pseudo-second order equation and the equilibrium isotherm was best described by the Langmuir model rather than the Freundlich and Tempkin model. In thermodynamic studies, the parameters of △G0 <0,△H0 >0 and △S >0 indicated that the adsorption process was spontaneous and endothermic with a increase in entropy.关键词
