Embodiment Construction

[0029] In order to make the implementation technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further elaborated.

[0030] The present embodiment provides a kind of rapid detection method of manganese, silicon, phosphorus element content in ferromanganese, and specific operation steps are as follows:

[0031] Weigh 0.1000g of the sample and place it in a 125ml tall conical flask, add HNO 3 (1+3) 40ml, heat and dissolve on an electric furnace at low temperature, and continuously add water until the sample is completely dissolved, boil to drive off nitrogen oxides, remove and quickly cool, and dilute with water in a 50ml volumetric flask as mother liquor.

[0032] (1) Determination of manganese: Take 2ml of the mother liquor and place it in a 350ml beaker, add 15ml of triethanolamine (1+4), 0.1mol L - 1 EDTA solution 10ml, 200g·L -1 Potassium hydroxide solution 10ml, oxygen 1 ~ 2min (or fully shake ...

Abstract

The invention provides a method for rapidly detecting the contents of manganese, silicon and phosphorus elements in ferromanganese. The method comprises the following steps of: measuring the light absorptivity of a measured substance at a specific wavelength by using a photometric method, carrying out qualitative and quantitative analysis on the substance, and obtaining corresponding element content values in a standard working curve of the manganese, silicon and phosphorus elements according to an absorption spectrum curve. Through weighing and dissolving once, a photometric method and a combined testing means are adopted, common analytical instruments and reagents are utilized, smoking treatment measures and complex and uneasy-to-control analysis steps are avoided, the operation procedure is simplified, the Mn, Si and P elements in the ferromanganese can be accurately, more quickly and jointly measured at low cost according to the simple, quick, accurate and cheap high-speed analysis principle and environment-friendly experimental requirements for low toxicity to personnel and low pollution to the atmosphere, the experimental period of the ferromanganese is greatly shortened, and the analysis cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of chemical analysis, in particular to a rapid detection method for the contents of manganese, silicon and phosphorus in ferromanganese. Background technique [0002] Mechanical products are inseparable from steel raw materials and castings. Ferromanganese is one of the most commonly used ferroalloys in the metallurgical and foundry industries as an alloying element additive and a deoxidizing and desulfurizing agent in steelmaking and casting production. After ferromanganese is purchased, quality testing is generally required so that technicians can master its true chemical composition and smelt qualified molten metal. For the detection of C and S elements in ferromanganese, a carbon-sulfur high-speed automatic analyzer can be used for rapid determination; for the three elements of Mn, Si, and P in ferromanganese, ammonium nitrate oxidation trivalent manganese titration method, silicon molybdenum blue photom...
