摘要： A sensor element suitable for colorimetric detection of anions in a sample, the sensor element comprising a water insoluble polymeric hydrogel having a polymer network defining a water permeable microvoid network, and an anion recognition dye (receptor) incorporated into the polymeric hydrogel. The anion recognition dye has a general formula (I),

Wherein R1, R2, R3 and R4 are each, independently, selected from H or an optionally substituted group consisting of lower alkyl, allyl, aryl, thioureas, urea, amide, ether, and X is S or O. An anion detection probe comprising a support that incorporates the sensor element and provided in the form of a dip-stick is also disclosed.
