应用
Devarda's Alloy is used as reducing agent in analytical chemistry for the determination of nitrates after their reduction to ammonia under alkaline conditions. It is also used in the quantitative or qualitative analysis of nitrates in agriculture and soil science before the development of ion chromatography. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, and agrochemicals.

备注
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store at room temperature. Incompatible with strong oxidizing agents.

产品说明

一般描述

Devarda 合金是一种还原剂,研究表明,其可用于将 NO3--N 或 NO2--N 还原为 NH4+-N,从而可用在总氮测定中。

应用

Reducing agent used for the determination of total nitrogen by the method of Kjeldahl. Reagent used for the reduction of alkaline solutions of chlorate to chloride
Devarda 合金可用于研究其作为还原剂对 Cp2TiCl 催化的苯乙烯活自由基聚合反应的作用,这是由环氧化物自由基开环引发的。
