The solubility of Fe(III), Al(III), Mg(II), Ca(II), and S in plant phosphoric acid was determined as a function of mole ratio of ammonia to phosphate (MR) and at temperatures of 25, 60, and 90 °C. For each metal ion, there is a unique MR characterizing the onset of a sharp decline in solubility and another characterizing the transition from sharp decline to a more gradual change. At any given temperature, these characteristic MR values generally increase with the following order: Ca(II) = Mg(II) > Al(III) > Fe(III). The temperature effects on the solubility behavior of these metal ions and S and the most likely cause(s) of such behavior were presented and discussed.

In inductively coupled plasma optical emission spectrometry (ICP -OES) it is widely acknowledged that the problem of spectral interference is a severely limiting factor in the analysis of matrices containing major constituents with line-rich spectra, such as titanium pigments, rare earth ores and steel (iron). The extent of this problem has led to many publications detailing specific interferencesl.2 and it is evident that line selection plays a crucial role in analysis by ICP -OES. Spectral interferences may be overcome by extraction of the analyte or interfering element3 or by matrix-matching of the standards.j These methods can be both time consuming and difficult and any simple alternative to solution pre-treatment would appear to be advantageous.It may be considered that any signal measured at the photomultiplier tube (PMT) that is not due to analyte emission constitutes a spectral interference. In the all-argon ICP, the "blank" spectrum consists of a broad-band continuum, a number of atomic argon lines and bands derived from water.5 A matrix may change the plasma background level at a given wavelength by any combination of three ways. These are a shift in the intensity of the continuum background, an enhancement due to the overlap of the wings of a nearby line and direct line overlap. The last of these presents the most serious case and cannot be directly solved by the proposed method. The problems posed by the first two, and a system capable of overcoming these, will be discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
