метод добавок

Определено содержание свинца в поверхностных горизонтах вдоль пяти автомобильных трасс четырех районов г. Саратова (Октябрьский, Заводской, Ленинский, Кировский) методом рентгенофлуоресцентного анализа. Для калибровки рентгенофлуоресцентного анализатора на свинец был использован метод добавок.

The problem of choosing a technique for determining ammonium ions, in concentrations above 1 gm/cdm, in surface waters, as in complex matrix, is one of the important problems of monitoring the condition of water bodies contaminated with ammonium salts. The solution to this problem will allow us to reliably assess the ecological condition of water bodies and the degree of reduction of environmental load during pollution elimination measures.

Modern methods of quantitative physical and chemical measurements should necessarily include procedures for quality control of research results. Recently, the procedure for quality control of measurements using control charts is gaining particular popularity in the practice of analytical measurements. To date, the methods of potentiometric studies operating in the territory of the Russian Federation, in most cases, do not include quality control using this control procedure.
