摘要：
It is shown that adsorption of thiourea at a Ni-electrode in acetate solutions is described by the Langmuir isotherm. A surface coverage near unity is achieved at a thiourea concentration of 5 x 10(-5) mol/l. Starting from nearly the same concentration, the process of electroless nickel deposition ceases to be initiated, evidently, due to covering the nickel's surface by thiourea.
