Abstract

The invention relates to the technical field of micro-element analysis, and provides a fly ash activity index detection method and system based on micro-element analysis. The method comprises the following steps: sampling a fly ash sample; analyzing the interference of granularity and moisture on microelement detection, and generating a preset granularity threshold value and a moisture content threshold value; crushing the screened sample by taking a preset particle size threshold value as a target to generate a first pretreated sample; drying the pressed sample by taking a preset water content threshold value as a target to generate a second pretreated sample; performing micro-element detection on the second pretreated sample to generate micro-element content information; and performing fly ash activity index analysis according to the content information to generate an activity index detection result. The method solves the technical problem of insufficient micro-element analysis precision caused by uneven particle size and moisture content fluctuation of the existing fly ash activity index detection method, and achieves the technical effects of effectively eliminating the interference of particle size and moisture on micro-element detection and improving the micro-element detection precision by optimizing the sample pretreatment process.
