中文摘要 | An efficient strategy to immobilize a non-aqueous soluble Hg2+ probe onto mesoporous silica is developed, and this immobilization is subject to several advantages regarding Hg2+ detection, such as improving sensing sensitivity and selectivity, extending application from an organic/aqueous mixture to a pure aqueous medium, and achieving removal of Hg2+ ions while detection. The selected Hg2+ probe, rhodamine B thiohydrazide, can be readily covalently immobilized onto mesoporous silica through a simple amide reaction and subsequently exhibits more than 10 times enhancement of sensitivity for Hg2+ (limits of detection are of 0.81 ppb in immobilized form versus 10 ppb in free form), and an adsorption capacity of 192 mg/g. Brunauer-Emmett-Teller and TEM characterizations demonstrate that the mesoporous structure can be well remained after Hg2+ probe modification and this feature is believed to be responsible for improved Hg2+ sensing properties.
