Continuous. 5 min sample/ wash). For high-resolution work in the estuary, the continuous sampling mode is preferred. The indophenol blue complex was measured at 630 nm with a colorimeter and the absorbance recorded on a chart recorder. 4. Mantoura and Woodward [66] overcame the problem of magnesium precipitation by ensuring a stoichiometric excess of citrate (about 120%). These workers believe that 'salt errors' occurring with estuarine samples originate from poor pH buffering rather than ionic strength variations.

C. I. ) NaOH) from an internal solution 0 . 1 M in ammonium chloride. A glass pHelectrode and a silver-AgCl reference electrode are immersed in the aqueous ammonium chloride. The ammonia in the sample passes through the membrane and the change in pH in the internal solution is detected by the glass electrode. The behaviour and characteristics, including theoretical detection limits, of the system are discussed. Le Corre and Treguer [71] developed an automated procedure based on oxidation of the ammonium ion to nitrite by hypochlorite in the presence of sodium bromide followed by spectrophotometric determination of the nitrite.
