Abstract
Methods of determining the individual concentrations of Na-CMC and PAA in their joint solution are studied. Modified Kjeldahl method to determine the concentration of PAA is proposed. Strong correlation of the refractive index and the concentration of Na-CMC is found. Weight method to determine common concentration is examined experimentally.
