PROBLEM TO BE SOLVED: To provide a method and device capable of detecting boron even in boron containing water in which a boron concentration is a small amount of being 1 ppm or below and coexisting irons having a concentration higher than boron exist.SOLUTION: Boron in boron containing water is adsorbed by a boron adsorbent, the boron is eluted from the boron adsorbent with an acid to generate boron concentrated solution, a boron concentration in the boron concentrated solution is detected, and a boron concentration in the boron containing water is operated from the boron concentration in the boron concentrated solution. |
