TURN ON-TYPE FLUORESCENCE SENSITIVE CHEMICAL SENSOR CONTAINING BORONIC ACID SELECTIVELY BONDED TO MERCURY ION, METHOD FOR PRODUCING SAME, AND MERCURY ION DETECTION METHOD USING SAME

摘要

The present invention relates to a turn on-type fluorescence sensitive chemical sensor containing a boronic acid selectively bonded to a mercury ion (Hg2+), a method for producing same, and a mercury ion (Hg2+) detection method using same. According to the mercury ion fluorescence detection sensor of the present invention, selective bonding to the mercury ion (Hg2+) for fluorescence is available even in a 100% aqueous solution and under the presence of another metallic ion in a solution in which an aqueous solution and an organic solution are mixed with each other, mercury ion (Hg2+) detection is facilitated by a turn on-effect in which the strength of fluorescence increases as the concentration of the mercury ion (Hg2+) increases. In addition, an irreversible covalence bond is formed through a metal exchange reaction between the boronic acid of the chemical sensor and the mercury ion so that mercury ion recognition is performed at the same time as removal of the mercury ion itself through separation of the chemical sensor from an analyzed object, which is eco-friendly. Accordingly, the present invention can be used effectively in various industrial fields in which mercury ion detection is required such as groundwater and river water systems and biosamples.;COPYRIGHT KIPO 2014
