【Abstract】 Nano-particles of silver sulfide were prepared by homogeneous precipitation. The nanoparticles obtained were characterized by scan-electron microscopy (SEM) and the optimum conditions of the preparation technology, were established by the method of orthogonal experimental design. The silver sulfide nano-particles prepared by the present method were used as active matter in the preparation of PVC-membrane silver ion selective electrode which was proved to have favorable electrochemical characteristics.更多还原
