This patent describes a method of making a cadmium sulfide membrane. It comprises preparing a cadmium sulfide colloid by introducing sulfide ions to an aqueous solution of 2.5 {times} 10 {sub {minus}3}M cadmium ions and polyphosphate molecules; concentrating the colloid by removing water from the colloid by concentration until the concentrated colloid has an electrical conductivity which exceeds twenty micro-mhos; drying the concentrated colloid until a solid membrane is produced.
