Studies were made of the effect of potassium concentration on the amount of potassium coprecipitation with BaSO4, and the effect of a surface active agent, Triton-X 100, on the coprecipitation of potassium with BaSO4. It was found that a log-log plot of concentration of KC1 in the solution phase vs the amount of potassium coprecipitated was linear indicating that the Freundlich adsorption isotherm was followed. This indicated that the amount of potassium coprecipitated was determined by adsorption on crystalline BaSO4. The addition of Triton-X 100 reduced the coprecipitation of potassium by as much as 20% but the improvement was limited by miceller formation at a Triton-X 100 concentration of approximately 0.3%.
