摘要: A novel effervescent-salt-assisted dispersive micro-solid-phase extraction using mesoporous hybrid materials was developed for the of minute traces constituents in complicated plant preparations. In this study, a special tablet containing carbon dioxide sources (sodium dihydrogenphosphate and sodium carbonate) sorbent (mesoporous materials) prepared. The effects different parameters influencing efficiency such as concentration salts, type material, pH diluent, desorption solvents were investigated optimized. Results show that proposed method green (water) solutions required low consumption sample amount obtained high enrichment efficiency. Moreover, under optimized conditions, tested tanshinones exhibited good linearity (r2 > 0.994) range 0.5 to 80 ng mL−1. limits detection values lower than 0.0803 pg UV–visible detection. successfully applied analysis trace compound Danshen dripping pill Danqi samples.
