Problems solved by technology
In complex samples, the introduction of chromatographic separation technology has significant advantages for the determination of sulfur, but the disadvantage is that the determination of sulfur usually requires complex derivatization of samples
Moreover, chromatographic instruments are expensive and need to rely on other detectors to complete the determination

Abstract
The invention relates to a material sensitive to sulfide and hydrogen peroxide as well as a preparation method and application thereof in detecting sulphions and the hydrogen peroxide in a solution and sulfureted hydrogen in a gas phase, belonging to the field of composite materials. The material has a PbO / SiO2 structure, wherein the mole ratio of Pb and Si is 1:6.67-100. The material sensitive to the sulfide and the hydrogen peroxide can fast and conveniently measure a minute amount of the sulphions and the sulfureted hydrogen and can also carry out oxidation treatment on a specific oxidant and then repeatedly use the specific oxidant or use the specific oxidant to measure the hydrogen peroxide after the measurement, thereby being more economic; and in addition, the invention has the advantages of convenient use in measuring the sulphions and the sulfureted hydrogen, low cost, high sensitivity, fast response and very good market prospect.
Description
Material sensitive to sulfide and hydrogen peroxide, its preparation method and use technical field The invention belongs to the field of composite materials, and in particular relates to a material sensitive to sulfide and hydrogen peroxide, a preparation method thereof, and an application of the material in detecting hydrogen peroxide and sulfide. Background technique Many types of sulfide are not only commonly used as a reducing agent, but also are often by-products of industrial or manufacturing processes such as papermaking, pharmaceuticals, and tanning industries, so they are widely found in natural water and wastewater . Due to the toxicity of sulfur and hydrogen sulfide, the determination of sulfur, especially hydrogen sulfide, has attracted the attention of the analytical community. Sulfur is a poisonous non-metallic element. Due to the use of coal and sulfur-containing substances, a large amount of sulfide enters water and air, causing more and more serious poll...
