摘要：
Ensemble of corrosion indices was combined to study the corrosion tendency of the drinking water supply at the University of Benin, Nigeria. The experimental results were analysed in terms of three corrosion indices-Langelier Index, Ryznar Index and Larson-Skold Index. According to the evaluation, the Langelier Index ranged from -5.569 to -3.684, Ryznar Index was between 13.340 and 16.418 while the Larson-Skold Index was between 1.191 and 31.750. Results indicated that the water may be corrosive. A regression of these indices on iron concentration (ppm) showed that Langelier Index, Ryznar Index and Larson-Skold Index have R 2 of 0.5868, 0.6577 and 0.7063, respectively. The positive correlation between iron levels and the corrosion indices suggested that iron levels were directly related to increase in corrosion tendency. © 2008 Springer Science+Business Media, LLC.
