水酸化ジルコニルを用いた亜ヒ酸イオンの吸着 ―ビーズ化による亜ヒ酸イオン吸着性への影響: Effect of Beading on the Adsorption Properties

In some parts of Asia, health damage has been reported due to using groundwater containing arsenic as drinking water. On the contrary, arsenic at a concentration exceeding the environmental standard value is detected in drilling work in Japan. Therefore, in this study, a bead-type adsorbent in which zirconyl hydroxide slurry was immobilized in calcium alginate was synthesized for the purpose of improving the handling property of arsenic adsorption. The performance of this adsorbent was evaluated under various conditions such as temperature, pH, and coexisting ions.
