摘要
用恒电位极化曲线法和旋转挂片失重法研究了３１６Ｌ、３０４不锈钢和２０号碳钢在３０℃，ｐＨ＝２．１０的含酚酸性废水中的耐蚀性。结果表明３１６Ｌ和３０４不锈钢具有优良的耐蚀性，而２０号碳钢不耐蚀。含酚酸性废水中所含甲醛对３１６Ｌ和３０４不锈钢有缓蚀作用，与相同ｐＨ的盐酸溶液中腐蚀速度相比，其缓蚀率为７０％。
篢he corrosion resistance of stainless steels（AISI316L，AISI304）and carbon steel in acidic waste water containing phenol（pH＝2．10，30 ℃）were investigated by the methods of poten- tiostatic polarization curves and weight losses of rotary specimens． Results show that stainless steels（AISI316 L， AISI304）have good corrosion resistance， but carbon steel（ Model 20）hasnot．Formaldehyde，which is contained in the acidic waste water containing phenol， may inhibit the corro-sion of stainless steels（AISI316 L， AISI304）． Compared with the corrosion rates which they are in the same pH hydrochloric acid solution， its inhibitor efficiency is 70％．
