采用XAD—7树脂吸附富集自来水和地面水中痕量邻氯酚和对氯酚。后用氢焰气相色谱法测定。在溶液的pH值小于6,流速为10毫升/分以内,平均吸附效率达94％和92％。甲醇、丙酮和(1+1)丙酮+乙醚混和液均有96％以上的淋洗效率。
Adsorption of trace amounts of ortho-chlorophenol and p-chlorophenol in tap water and surface water using XAD-7 resin. After hydrogen flame gas chromatography. With a solution pH of less than 6 and a flow rate of 10 ml / min, the average adsorption efficiency was 94% and 92%. Methanol, acetone and (1 + 1) acetone + ether mixture have a leaching efficiency of more than 96%.
