Method and apparatus for monitoring impurity content to improve material production efficiency

Abstract

A method for monitoring impurity content to improve material production efficiency includes: removing adsorbent impurities and oxides on a surface of a metal block; dissolving the metal block with a mixed solution of nitric acid and hydrochloric acid but not dissolving impurities in the metal block to produce a test liquid; passing the test liquid through a transparent flow channel; recording a particle image of the impurities in the test liquid in the transparent flow channel with an optical system; and analyzing the particle image by image recognition to calculate a concentration of impurities contained per unit mass of the metal block. An apparatus for monitoring impurity content to improve material production efficiency is also provided.
