Perchloric acid is a mineral acid with the formula HClO4. Usually found as an aqueous solution, this colorless compound is a stronger acid than sulfuric acid, nitric acid and hydrochloric acid. It is a powerful oxidizer when hot, but aqueous solutions up to approximately 70% by weight at room temperature are generally safe, only showing strong acid features and no oxidizing properties. Perchloric acid is useful for preparing perchlorate salts, especially ammonium perchlorate, an im… Web反相hplc法测定氨酚曲马多片各组分含量; 高效液相法测定驻车丸中小檗碱的含量; 反相hplc法测定阿奇霉素软胶囊的含量; 火焰原子吸收法测定返魂草中6种元素含量; hplc法测定冰黄软膏中盐酸小檗碱的含量; hplc法测定贯叶金丝桃中金丝桃素的含量论文
