Of the methods in common use, the two wet oxidation methods offer the best possibilities for further development. The photo-oxidation method in particular is well suited to automatic analysis. In the version of the total organic carbon method published by Collins and Williams [30] the effluent from the quartz photolysis coil could as easily be diverted to the nitrate analysis unit if inorganic nitrogen were also measured, organic nitrogen could become a routine automatic method.

Evidence for the existence of Au(N03)3 seems to be based on a report by Field and Hardy52 who treated hydrated gold nitrates successively with HN03 and N205. Although the gold content corresponded to the trinitrate, no quantitative nitrate analysis was performed. Further information is lacking. 

The composition of the THF complexes of the lanthanide trichlorides is established by dissolution of a weighed amount of each compound in water and determination of chloride potentiometrically with aqueous silver nitrate. Analysis for the lanthanide is effected by titration with disodium ethylenediaminetetraacetate using xylenol orange indicator after appropriate buffering of the solution.The IR spectra of all the trichlorides show intense bands at 1020 and 880 cm" (see below), indicative of coordinated THF. ... 

The first two SMETs datasets evaluated for nitrate analysis in RM13 were obtained by the same laboratory with two different methods 1, HACH Kit Colo (Nitraver 5) (laboratory code 18a) and 2, Pastel UV SECOMAM (Spectrophotometry UV + deconvolution) (laboratory code 18b). The two results are encircled on Figure 5.2.1.
