Concentration Of Impurities

When snow is made from sewage effluent, the impurities become concentrated in the early melt leaving the later runoff relatively pure. This could provide a low cost method of separating nutrients from secondary sewage effluent. Laboratory experiments showed that the degree of concentration was largely independent of the number of melt freeze cycles or initial concentration of impurity in the snow. The first 20% of melt removed with it 65% of the phosphorus and 90% of the nitrogen from snow made from sewage effluent; and over 90% of potassium chloride from snow made from potassium chloride solution. Field experiments with a salt solution confirmed the laboratory results.

IrCl3(PEt3)3 is readily converted to IrHCl2(CO)(PEt3)2 by treatment with carbon monoxide in hot acetone, ethanol, or 2-methoxyethanol. Perchlorate, tetrafluoroborate, and tetraphenylborate salts containing the [IrCl2(CO)(PEt3)3]+ cation have been prepared, but attempts to obtain salts containing the [IrHCl(CO)(PEt3)3]+ cation give only the neutral hydride, IrHCl2(CO)(PEt3)2. The reactions of [IrCl2(CO)(PEt3)3]+ with ethanol, water, lithium aluminum hydride, aqueous potassium chloride solution, and sodium alkoxides are described.

Liquid from eggs of various qualities was frozen at −40° F. and stored at 10°, 0°, and −10° F. for 12 months. Powder produced from the defrosted samples was assessed by fluorescence and potassium chloride solution solubility measurements, which showed that liquid from musty or incubator reject eggs gave a less desirable powder than liquid from Grade A, Grade C, or cracked eggs; increase in time of frozen storage decreased the quality of the resulting powder; if frozen storage extended beyond six months, the lowest storage temperature was most desirable; and method of packaging (in Reynold's Metal A-10, or in wax paper with or without added ice) had no effect on the quality of the powder produced. If drying conditions were held constant, increased dilution of the defrosted egg before drying resulted in a poorer powder. It was shown that freezing or defrosting operations should be completed within about one hour.

Abstract Niacinamide is extracted from multivitamin preparations with sodium bicarbonate solution. The extract is mixed with Celite and packed into a chromatographic column. The vitamin is eluted with 10% re-propanol in ether and the eluate is evaporated to dryness in the presence of hydrochloric acid. The residue is dissolved in potassium chloride solution and diluted to volume. The polarogram, from –1.40 to –1.90 v, is recorded on a polarograph equipped with a dropping mercury electrode and an H-cell with a saturated calomel reference cell. Additional assays with chemical and microbiological methods showed comparable results. The method is sensitive to 2 mg niacinamide.
