| Abstract: | In this paper,the author states the monitor means to wash close circulative technical system and arsenic of furnace gas in high-interference ion conditions by using sulfuric acid water. This way makes the lowest examination density decreased by improving equipment of fixing arsenic and choosing arsenic high-interference ion of shelter reagent trial to recommend way of AG(DDTC) by Nanjing Chemistry & Industry Academy. This difficult issue has been solved. It is no way to measure using sulfuric acid water to wash close circulative technical system and arsenic of furnace gas by adopting present methods. Meanwhile,cost of shelter reagent has been falled tremendously. This article offers research results about this approach.. Finally,the author gives operating program about it. |
