摘　　要：本文利用富含生物碱的中草药天然植物萝芙木作为原料,通过传统酸提法对生物碱进行提取,并通过失重法和电化学方法对提取物在1.0 mol/L H2SO4腐蚀介质中对碳钢的缓蚀性能进行评价。实验结果表明:萝芙木提取物是一种混合型的缓蚀剂,能够在酸性介质中对Q235碳钢表现出良好的缓蚀性能,当添加量为37.5 mg/L时,缓蚀效率可达到64.89%。In this paper, a natural Chinese herbal medicine rich in alkaloids, Rauvolfia, was used as raw material to extract the alkaloids by traditional acid extraction method. The corrosion inhibition performance of the extract on carbon steel in 1.0 mol/L H2SO4 corrosion medium was evaluated by weight loss method and electrochemical method. The results show that Rauvolfia extract is a mixed corrosion inhibitor;it shows good corrosion inhibition performance to Q235 carbon steel in acid medium;when the addition amount is 37.5 mg/L, the corrosion inhibition efficiency can reach 64.89%.
