介绍了一种检测浆粕中重金属含量的方法,即通过烧灰法将浆粕灰化,再加入盐酸和醋酸溶解,用等离子体原子发射光谱(ICP-OES)仪检测浆粕中重金属元素的含量。该方法能够准确测定铜、镉、铁、锰、钼、镍等6种重金属元素的含量,具有重复性能好、检出限低、操作简便的优点。
A method for detecting the content of heavy metals in pulp is introduced, that is, the ashes are pulverized by the ashing method, dissolved in hydrochloric acid and acetic acid, and the content of heavy metal elements in the pulp is measured by ICP-OES content. The method can accurately determine the contents of six heavy metal elements such as copper, cadmium, iron, manganese, molybdenum and nickel, and has the advantages of good repetition performance, low detection limit and simple and convenient operation.
