| titleOfInvention | Arsenic nano-particles, preparation method thereof, system and method for preparing arsine through electrolysis |
| abstract | The invention provides an arsenic nano-particle, a preparation method thereof, a system and a method for preparing arsine by electrolysis. The preparation method comprises the following steps: step S1, heating in a closed container under vacuum condition to sublimate the arsenic simple substance to form arsenic vapor in a plasma state; step S2, filling inert gas or nitrogen into the closed container to increase the pressure in the closed container; step S3, contacting the arsenic vapor with a cooling device in the closed container, and condensing the arsenic vapor to form arsenic nanoparticles. The preparation method utilizes the metal vapor atoms to collide with gas atoms at high temperature to lose energy and condense to form nano-sized clusters, and the nano-sized clusters are aggregated under a quenching condition to form nano-scale arsenic nano-particles. The obtained arsenic nano-particles have the surface unsaturation and high reactivity of hydrogen ions, and a large amount of catholyte does not need to be prepared when the arsenic nano-particles are applied to the preparation of arsine by electrolysis, so that the generation of arsenic-containing waste liquid is reduced, and the generation of hazardous waste is reduced. |
