PRECONCENTRATION AND SEPARATION OF ULTRA-TRACE AMOUNTS OF MERCURY(II) USING ULTRASOUND-ASSISTED CLOUD POINT-MICRO SOLID PHASE EXTRACTION BASED ON MODIFIED SILICA AEROGEL WITH [1-(3,5-DICHOLOROPHENYL)-3(2-ETHOXYPHENYL)] TRIAZENE
ABSTRACT In this study, a separation-preconcentration procedure, ultrasound-assisted cloud point-micro solid phase extraction (USA-CP-MSPE) with modified silica aerogel, was developed for the determination of Hg (II) from water samples- modified silica aerogel (SA) adsorbent coupled with metal chela...
