Abstract: A mercury selective fluorescent chemosensor for detecting mercury ions by a compound represented by formula 1 and a novel fluorescent sensitive compound prepared by introducing two aminopyrene functions as a fluorescent sensitive moiety into a binding site of the compound of formula 1 is used for selectively detecting mercury ions are provided. The mercury selective fluorescent sensitive chemosensor is a switch type chemosensor having ON-OFF-type Hg2+-selective fluorescence quenching behavior and is not affected by other coexistent metal ions. Changes in fluorescence of the compounds of formula 1 were analyzed by ratiometric approach using monomer and excimer emissions of the pyrene fluorophore to selectively signal the concentration of mercury ions. The chemosensor can detect mercury ions in a micromolar unit even in a solution including an excess of water. Accordingly, the mercury selective fluorescent chemosensor for detecting mercury ions can be used effectively in environmental and medical applications.

Abstract: An automatic washing machine having an improved structure. The sprinkling member for repeatedly sprinkling the washing water into the dehydrating tub comprises a removable washing tub lid, an adapter for permitting the washing water to be fed therethrough and a guide member forming, in cooperation with the washing tub lid, a sprinkling nozzle through which the washing water is sprinkled into the dehydrating tub. The lint filter filters off lints generated in the washing cycle and permits the filtered lints to be automatically removed therefrom so as to be drained off the washing machine along with the drained water. The circulation pump circulates the washing water and is connected to the washing tub and the sprinkling member in such a manner that it permits the washing water in the washing cycle to be drawn up to the sprinkling member through the lint filter and also permits the used washing water in the draining cycle to downwardly pass through the filter so as to be drained off the washing machine.
