arsenicsとは 意味・読み方・使い方

The arsenic acid recovered by deposition through reduction of the arsenics has a large particle diameter and a high-purity arsenious acid can be obtained by removing impurities therefrom through washing.例文帳に追加

砒酸の還元により析出回収した亜砒酸は粒子径が大きく、洗浄して付着不純物を洗い流すことにより高純度の亜砒酸が得られる。 - 特許庁

In the method of producing arsenious acid, the total concentration of pentavalent and trivalent arsenics is controlled to 40-50 g/l when the arsenic acid in the solution containing the arsenic acid and arsenious acid is reduced by sulfurous acid gas.例文帳に追加

砒酸と亜砒酸を含む溶液中の砒酸を亜硫酸ガスで亜砒酸に還元する際に、５価と３価の砒素の合計濃度を４０〜５０ｇ／ｌに制御する。 - 特許庁
