Estimation of organic acid anion concentrations and evaluation of charge balance in atmospherically acidified colored waters.
Original language description
Organic acid anion concentrations (R<sup>-</sup>) represent an important part of the anion pool in colored surface waters. When the estimation of R<sup>-</sup> is based on a charge balance approach, R<sup>-</sup> cannot be used for the ionic balance control of the correctness of the analyses. The following simple approach for R<sup>-</sup> estimation is independent of the charge balance. In this approach, R<sup>-</sup> is estimated using the concentration of ionizable carboxylic groups per mass of DOC (X<sub>I</sub>), DOC concentration and pH. The X<sub>I</sub> value is estimated as the difference between the average total concentration of carboxylic groups per one mg of DOC of natural fulvic and humic acids (10 eq mg<sup>-1</sup>) and the concentration of metal-complexed carboxylic groups. The latter concentration is assumed to be equal to organically bound Al and Fe. When applied to the Bohemian Forest stream waters, the average ( standard deviation) X<sub>I</sub> is 6.2 .mult. 0.8 e
