Acoustical parameters of polyacrylamide with sodium (meta) silicate and potassium silicate solution at 303 K

Abstract

The ultrasonic velocity (U) and density (ρ) have been measured in mixtures of polyacrylamide solution in sodium meta silicate and potassium silicate solutions in different concentrations at 303 K. Based on the data obtained, the adiabatic compressibility (β_ad), intermolecular free length (L_f), acoustic impedance (Z) and relative association have been calculated. Variations of the acoustical parameters in polyacrylamide are studied with silicate solutions. The results have been discussed in terms of various interactions present in these mixtures and relative associations in the components.
