摘要
采用电化学阻抗谱、极化曲线及Mott-Schottky图研究了十二烷基二甲基苄基氯化铵(1227)杀菌剂在模拟冷却水中对硫酸盐还原菌(SRB)的腐蚀抑制作用。结果表明,随着1227浓度的增加,不锈钢电极的阻抗值逐渐增大,钝态电流密度J_p则逐渐减小。1227浓度为20 mg·L~(-1)时,J_p从不含1227的42.46μA·cm~(-2)减小到14.91μA·cm~(-2)。而载流子浓度ND和NA也随着1227浓度的增加呈下降的趋势,在1227浓度为50 mg·L~(-1)时,不锈钢电极的载流子浓度ND和NA分别从不含1227的17.72×10~(21)cm~(-3)和28.15×10~(21)cm~(-3)减小到2.07×10~(21)cm~(-3)和2.49×10~(21)cm~(-3)。说明1227能够有效地降低SRB对不锈钢的腐蚀作用,较好地控制微生物腐蚀。
