An investigation is reported on the relation between the size and ζ potential for silver nanoparticles prepared in aqueous solution of carboxymethylcellulose to pH of the solution by virtue of dynamic light dissipation. The changes in the size distribution for nanoparticles and their ζ potential were monitored over time. The size of particles was found to degrease linearly with increasing pH; a similar effect was created by the maturation of colloidal solution. The ζ potential of the maturation process tended to take an identical value for all hydrosol samples studied. A procedure is proposed for the numerical calculation of the relative concentration of nanoparticles that is applicable for the investigation of samples with various types of distribution for particle sizes. The degree of reduction for silver ions was found to depend significantly on the quantity of AgNO3 presented and the ration between the precursor and the reducing agent.
