摘要: Abstract The effects of flow rate, direction, ratio, pressure, membrane area, channel depth and shape on the optimization gas-diffusion flow-injection systems are described in detail. A nonreacting chemical system, chlorine dioxide, was used to study physical dispersion systems. It found that slow rates shallow channels optimal. Stopped-flow conditions a system may not be worth cost time. For which analyte is consumed, optimized parameters included stopped flow.
