Abstract
A simply and accurate analytical method was developed to determination the carbon content in silica-supported materials. The principle of this method was to oxidize sample by a strong oxidant like potassium dichromate to produce carbon dioxide and this gas is absorbed into an alkaline solution for subsequent titration. The repeatability and the recovery of this method fell into the required range (% RSD <1.3 % and 98-102 % in recovery) of AOAC International. The chloride content of up to 100 mg did not give any influence. The developed procedure was applied to determine the carbon content in octadecyl-modified silica samples.
