The indirect spectrophotometric determination of 0.8-7.2 ppm calcium in the presence of magnesium, phosphate and sulphate by flow injection analysis (f.i.a.) is described. The method is based on the exchange reaction between the calcium and the zinc complex of ethylene glycol-bis(2aminoethylether)te
Standard calciwx solution, 80.0 pg/nzl. Dissolve 0.1998 g of pure calcium carbonate in a slight cxccss of hydrochloric acid and dilute to I 1.
A sequential injection analysis method is developed for the determination of calcium in white water of a paper machine. The determination is based bn the formation of a coloured complex between Ca\*+ and o-cresolphthalein complexone, which is monitored spectrophotometrically. Parameters of the met
