摘要
process to obtain a suspension of chitosan - silver with solution of chitosan in acetic acid is that the solution of chitosan in acetic acid with continuous stirring is added to an aqueous solution of sodium tripolifosforanu, after which the ph is from 4 to 5 and heated together to tempe ratury from 20 to 80u00b0c, after which the suspension with continuous stirring the aqueous solution of silver nitrate (v),and then the aqueous solution of ascorbic acid and the formed mixture is heated to the temperature of 40 to 80u00b0c. the subject invention is also nanokompozyt chitosan - silver.
