摘　　要：本文选用滤膜采样技术 ,采集生产环境空气中高氯酸铵微粒并溶解在蒸馏水中 ,用已知过量的亚甲基兰 (以下简称亚甲兰 )与水溶液中的高氯酸根离子反应 ,生成高氯酸亚甲兰沉淀。分离沉淀 ,对剩余的亚甲兰进行比色测定 ,从而间接测定高氯酸铵含量。本方法具有操作简便 ,结果准确可靠 。Ammonium perchlorate was collected from the air of production environment and dissolved in the distilled water by filler film.The known excess of methylene blue was used to react with the soluble perchlorate,and precipitation of methylent blue perchlorate was formed.The residual methylent blue was estimated and thus the concentration of ommonium perchlorate was indirectly determined.This method is simple and rapid with accurate results.
