Experimental data showed that metal levels increased exponentially with time, with the sharpest increase occurring over the first 20–24 h. Metal levels may continue to increase following well beyond 24 h of stagnation. Copper levels increased until dissolved oxygen fell below 1 mg l−1 after which copper levels fell. Results showed that stagnation behaviour is complex in nature, difficult to predict and dependent on water chemistry. Experimental data fit well to a radial diffusion model when a diffusion barrier term is considered. brass, copper, corrosion, diffusion, lead, stagnation time This content is only available as a PDF. © IWA Publishing 2000 You do not currently have access to this content.
