Highly selective and sensitive chromium(III) membrane sensors based on 4-amino-3-hydrazino-6-methyl-1,2,4-triazin-5-one as a new neutral ionophore

A poly vinyl chloride membrane sensor for chromium(III) ions was prepared based on 4-amino-3-hydrazino-6-methyl-1,2,4-triazin-5-one (AHMTO) as a membrane carrier. The sensor has a linear dynamic range of 1.0 × 10 −6 to 1.0 × 10 −1 M, with a Nernstian slope of 19.7 ± 0.3 mV decade −1, and a detection...

Zusammenfassung:A poly vinyl chloride membrane sensor for chromium(III) ions was prepared based on 4-amino-3-hydrazino-6-methyl-1,2,4-triazin-5-one (AHMTO) as a membrane carrier. The sensor has a linear dynamic range of 1.0 × 10 −6 to 1.0 × 10 −1 M, with a Nernstian slope of 19.7 ± 0.3 mV decade −1, and a detection limit of 5.8 × 10 −7 M. It has a fast response time of
