摘要: Abstract A study was made of the adsorption characteristics triethyl phosphate (TEP), dimethyl (DMP), and orthophosphate (OP), from aqueous solution onto activated charcoal cloth (ACC). The isotherms obtained were a Langmuir type and, at neutral pH, 293°K, equilibrium capacities 2430, 107, 44.6 μmol g−1 TEP, DMP, OP solutions, respectively. DMP found to be strongly pH dependent. It is suggested that this dependence arises because combination their pK values charge on surface in media. latter established by measurement electrophoretic mobility as function pH. No effect evident TEP adsorption. Prior reaching it shown proportional ( time ) 1 2 indicating intrafibril (particle) diffusion.
