The Mean

The use of a univalent cation glass electrode for determining ammonium in water is described. The method enables direct determination of ammonium ion in concentrations above 0.5 mg/liter without any dilution or pretreatment of sample. A constant background of Na+ and K+ in samples is required, with concentration of potassium being lower than that of ammonium. For several types of natural and enriched waters with ammonium content up to 40 mg/liter NH4-N, the mean error by the method was ±4.9%.

Abstract A rapid method suitable for the direct titrimetric determination of calcium in icteric sera is presented. The major portion of serum chromogens are oxidized to colorless products by either a mixture of hydrogen peroxide and potassium ferricyanide or by sodium hypochlorite. Ethylenediamine tetraacetic acid (EDTA) is the titrant used and either calcein or Cal-Red is suitable as the specific calcium indicator. Results compare favorably with those obtained by the method of Clark and Collip.
