“…Numerous procedures are available for the determination of the nitrite ion in solution. Good reviews can be found in the literature (1)(2)(3). The spectrophotometric procedures normally recommended involve the diazotization of an aromatic amine and the coupling of the diazo compound with a naphthalene derivative to form a highly colored, relatively (3) E.

“…Most of these elements exhibit oxide and hydroxide band emission in this region, the intensity of emission being generally most prominent in hydrogen flames. For this reason, the analytical use of the 540.8-µ band is perhaps unrealistic except for limited applications such as those mentioned (2,3). On the other hand, the atomic lines and the ultraviolet band are relatively free of spectral interference from other species which may be present in samples.…”

Flame conditions which permit the excitation of the atomic spectrum of phosphorus are reported. The analytical utilities of the atomic spectra and the phosphorus monoxide bands are compared for different flame types and detection limits are given. Interference effects are evaluated and a simple batch ion exchange separation is given for the elimination of these effects. The method has been applied to the analysis of representative biological materials and the results are shown to compare favorably with colorimetric results.

The effect of brown marine algae (BMA; Sargassum dentifebium) as alternative feed source for pullets was studied in three processed and at three concentrations in the pullets from 14-42 weeks. The processing forms were sundried brown marine algae (SBMA), sundried and boiled brown marine algae (BBMA) and sundried and autoclaved brown marine algae (ABMA). The concentrations of BMA were 2%, 4% and 6% that composed 10 treatments along with control. Each treatment was replicated 6 times using 30 pullets per treatment. Different criteria on pullets and eggs, including feed intake, body weight, feed conversion efficiency, laying rate and egg mass and quality were studied. Results indicated that BMA could be used up to 6% in the pullets diets from 14 to 42 weeks without adverse effects (P≥0.05) on sexual maturity (139-142 days), laying rate (80.7-87.9%), egg mass (44.99-51.86 g/hen/day), feed conversion ratio (2.468-2.868 kg feed/kg egg) and Haugh unit (82.9-90.6) and shell percentage (8.61-9.87%). Furthermore, egg yolk color and calcium content in eggshell were improved (P≤0.05) by 12.31% and 9.1%, respectively.

“…Last, but not least, molecular absorption and emission of some phosphorus-containing compounds, such as PO and HPO, has been investigated for the direct determination of phosphorus. [35][36][37][38][39] Unfortunately, the method suffers from strong interferences and poor stability.…”

PO molecular absorption bands, produced between 200 nm and 350 nm in an ordinary airacetylene flame, were investigated using a high-resolution continuum source absorption spectrometer. The bands comprise sharp structures with half-widths similar to those of common atomic lines. Four PO band heads, located at 246.40 nm, 247.78 nm, 324.62 nm and 327.04 nm, were selected and systematically evaluated with regard to the determination of phosphorus. Nitric, sulfuric, hydrochloric and hydrofluoric acids, with concentrations of up to 5% (v/v), and up to 2000 mg L À1 solutions of Al, Co, Cr, Cu, Fe, K, Mn, Na, and Ni, were examined for possible matrix or spectral interferences. The only serious spectral interference found was the disturbance of the PO band head at 324.62 nm by the 324.754 nm Cu resonance line at high concentrations. Apart from this, a suppression effect on the PO absorption caused by the presence of Ca and Mg was observed and will be discussed in a separate paper in this journal. The determination of phosphorus via molecular PO absorption proved to be a rapid and reliable method. Performance was verified by analyses of standard reference materials, where good precision and accuracy were achieved. The limit of detection for phosphorus was found to be 1.3 mg L À1 for a measurement time of 25 s, using the PO band head at 324.62 nm. The linear dynamic range covers more than three orders of magnitude.
