Methods of Assessment of the Fractional Distribution of Organic Substances in Natural Waters: A Membrane—Oxythermographic Method

Аннотация

A review of methods for the assessment of the fractional distribution of organic substances in natural waters is presented. The problem is usually solved by combining methods of separation into fractions with those of the quantitative determination of substances in the fractions obtained. There is also an original approach based on a combination of methods of membrane filtration and oxythermography; an example of using this approach is presented.
