PROBLEM TO BE SOLVED: To provide a technique for analyzing precisely an element contained in a solution quantitatively by a fluorescent X-ray analytical method. SOLUTION: In this method , a concentration of the element in the solution is analyzed quantitatively by dropping a solution sample on an organic polymer film applied with a hydrophobic agent, followed to be dried, and by analyzing a residue thereof by the fluorescent X-ray analytical method, a standard solution is prepared by a method, and analyzed, and a correlation between an X-ray intensity and the concentration is made clear to verify a lower limit of quantitative determination and precision. The method is applied in a chemical analytical field such as quality control of beverage, environmental evaluation as to inland water such as river water, lake water, lagoon water, and ground water, and is also utilized as a technique for screening easily the element concentration in the sample solution for executing highly precise solution analysis in a laboratory.
