Radiolytic reduction of silver, copper and cadmium ions and the subseq
uent formation of their clusters was studied in aqueous gelatin or car
boxy methyl cellulose (CMC) solutions. Presence of gelatin or CMC in t
he solution affects the early processes. The rate of reduction by hydr
ated electron reduces due to complexation. However, when the ratio of
silver ions to monomeric chains decreases over a-certain limit the pro
cess of reduction inhibits completely. The effect of ionic strength or
pH and the reducing radical on the rate of formation of colloidal Cu
and Cd is also discussed. (C) 1998 Elsevier Science Ltd. All rights re
