Fixed bed adsorption of chromium and the Weibull function

Fixed bed adsorption of toxic metal ions such as chromium is a research area current interest. Mathematical models are routinely used to summarize breakthrough results ions, which often display varying degrees curve asymmetry. This work introduces the Weibull function simple model for correlating asymmetric curves chromium. The similar widely Bohart-Adams in several aspects. For example, they both produce sigmoid or S-shaped curves. Their mathematical forms can be linearized and linear regression then estimate their parameters. However, function, unlike model, track trajectory data. Applying published data chromium, this article illustrates its outright superiority versus representing highly Both equations provide satisfactory fits exhibiting moderate degree
