Synthesis of β-Cyclodextrin-2,4-dihydroxyacetophenone-phenylhydrazine and Its Application

Abstract

A novel host reagent of b-cyclodextrin-2,4-dihydroxyacetophenone-phenylhydrazine(b-CDP-DHPH) was synthesized and characterized by IR and 1 H NMR spectra. A highly selective and sensitive spectrofluorimetric determination of trace amounts of cadmium was proposed based on the reaction between Cd 2+ and b-CDP-DHPH at pH 10.0. The molar ratio of b-CDP-DHPH to Cd 2+ was 1:1. The linear range of this method was 0.56-120 mg·L -1 with a detection limit of 0.20 mg·L -1 . The interferences of 39 common ions in the determination of cadmium were investigated, and the results showed that the host reagent had a quite high selectivity. This method was rapid and simple in determination of trace amounts of cadmium in mineral, tap and river water.

Sensor activity and logic behavior of dihydroxyphenyl hydrazone derivative as a chemosensor for Cu 2+ determination in alkaline aqueous solutions

“…Both compounds absorb in a range of 290-425 nm with well pronounced maximum at 372 nm ( Figure 1A). This band is attributed to the π→π* transition which is usual for compounds of similar nature [61,62]. In the presence of hydrochloric acid the absorption spectra of 2 and …”
