Abstract

Abstract A more sensitive and accurate method for measuring very low concentration of cationic copolymer nanospheres is established by measuring the conductivity of cationic nanosphere dispersion. The effect of the nanosphere concentration on the conductivity was investigated during the adsorption process. The results indicate that the relationship between the concentration of nanospheres and bromide ions is coincidence with linear relation. At very low nanosphere concentrations, the conductivity increases with increasing the nanosphere concentration, exhibiting a linear relationship. However, the limiting molar conductivity of nanosphere decreases with increasing nanosphere concentration. The obtained adsorption data were fitted to the Langmuir adsorption isotherm. The SEM images show that the nanospheres form a uniform monolayer on cotton fiber surfaces. The saturated amount of the nanospheres on the cotton fibers is 63.49 mg/g.
