【Abstract】 Plant conditions of the calcium hydroxide adsorbent, type and quantity of the indicators, and their effects on the behaviour of the adsorbent were discussed in this paper. Through multiple tests, the best indicator and the best raws proportion were picked out, thus a new calcium hydroxide adsoubent, that performs satisfactorily and changes its color sharply was obtained.更多还原
