Embodiment 1

[0034] In the present embodiment, the assay method of gallium content in 304 antibacterial stainless steels is as follows:

[0035] (1) Measured on an inductively coupled plasma atomic emission spectrometer (Optima7300DV, Perkin Elemer, USA), the optimized working conditions of the instrument are as follows: the high-frequency generator power is 1.2kW; the plasma gas flow rate is 16mL / min; The air flow rate is 1.0mL / min; the auxiliary air flow rate is 0.2mL / min; the solution lifting volume is 1.5mL / min; the integration time is 2-5s; the observation direction is axial; the observation height is 11mm;

[0036] (2) Reagents:

[0037] (2.1) Gallium single element standard solution (1000 μg / mL, National Iron and Steel Materials Testing Center Iron and Steel Research Institute);

[0038] (2.2) Iron single element standard solution (10mg / mL): prepared by dissolving metallic iron with a purity of not less than 99.99wt% in hydrochloric acid and nitric acid;

[0039] (2.3) Hydrochlori...

Abstract

The invention belongs to the technical field of alloy macroelement analysis, and particularly provides a method for determining the gallium content in antibacterial stainless steel, so as to fill the blank of the current method for detecting the gallium content in the antibacterial stainless steel. The method comprises the following steps: dissolving gallium-containing antibacterial stainless steel by using aqua regia, eliminating iron matrix interference by using a matrix matching method, and eliminating ferrospectral line interference by using a matrix blank as a standard working curve blank, thereby establishing an analysis and detection method for determining the gallium content in the stainless steel by using the inductively coupled plasma atomic emission spectrometry. The method is easy and convenient to operate, the test result is good in precision and high in accuracy, and the detection requirement of gallium in novel antibacterial stainless steel can be met.

Description

technical field [0001] The invention belongs to the technical field of alloy constant element analysis, and particularly provides a method for measuring gallium content in antibacterial stainless steel. Background technique [0002] Antibacterial stainless steel is to add a certain amount of antibacterial metal elements to ordinary stainless steel. After a special heat treatment process, the elements are evenly distributed inside the material, thus endowing it with antibacterial function. Gallium-containing antibacterial stainless steel is based on the traditional copper-containing antibacterial stainless steel, adding 0.2wt% to 3.0wt% metal gallium, which has the effect of inhibiting bacterial reproduction, so that it works synergistically with copper to antibacterial, thereby improving the antibacterial performance of the material. The content of gallium has a significant impact on the antibacterial performance of stainless steel, so it needs to be accurately determined. ...
