Abstract
A cellulose acetate based optode membrane containing 4-dimethylamino-4 '-octylazobenzene as an acid-base indicator is described. Other essent ial components of the membrane for a fast-responding and durable senso r are diethyl phthalate, triethyleneglycol and potassium tetrakis(4-ch lorophenyl)borate. Factors affecting the sensor behaviour are discusse d and an application in a flow-cell is demonstrated.
