纳米硫化银离子敏感材料的研制

PREPARATION OF NANO-PARTICLES OF SILVER SULFIDE AS ION-SENSITIVE MATERIAL

采用均相沉淀法研制了硫化银纳米粒子,并用扫描电子显微镜(SEM)对粒子进行表征,确定了制备硫化银纳米粒子的最佳工艺路线;用硫化银纳米粒子研制了PVC膜银离子选择性电极,试验表明,此种电极具有良好的性能。

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.
