Cigarette butts prevent corrosion

Wednesday, 19 May 2010

According to one estimate, some 4.5 trillion cigarette butts from spent smokes make their way into the environment every year. In this study, the cigarette butts are applied as corrosion inhibitor.

Still, humans are inadvertently carpeting the planet in cigarette butts. That is billions of cigarettes flicked, one at a time, on our sidewalks, beaches, nature trails, gardens, and other public places every single day. One of effective ways to reduce pollution is introduced by recycling the cigarette butts. In the study of Jun Zhao and his colleagues from School of Energy and Power Engineering in China, the cigarette butts are applied as corrosion inhibitors for N80 steel, used for pipelines, at 90 °C in hydrochloric acid. Weight loss and electrochemical techniques are used to evaluate the corrosion inhibitive effect of cigarette butt water extracts. Results show that the inhibition efficiencies arrive at 94.6 % and 91.7 % in 10 % and 15 % (wt %) HCl solution, respectively, by adding 5 % (wt %) inhibitor.
