摘 要：In this work, a surfactant, benzalkonium chloride(BAC), was used to study its effects on both the growth of Chlorella vulgaris and the corrosion caused by its biofilm. Experimental results indicated that BAC at a low concentration of 3 mg/L suppressed C. vulgaris growth and achieved 81% corrosion inhibition based on weight loss reduction. The inhibition effects increased when the BAC dosage was increased.At 30 mg/L, the corrosion inhibition increased to 95%. Electrochemical results supported surface pitting analysis, weight loss results data and confirmed the corrosion inhibition.
