Self-diffusion coefficients of water in pure water and in aqueous solutions of several electrolytes at various temperatures have been measured using the diaphragm cell method with deuterium as tracer. Electrolytes investigated were ammonium chloride, ammonium sulphate, potassium nitrate, potassium chloride,...
Most SISEs have contained potassium chloride because this compound acts as a salt inhibitor in the process of water uptake and escape. This, in addition to being a waste-removal factor, has also accumulated on the light-accepting surfaces. The white-coated surface would reduce light absorption ...
