Method for degrading triphenyl phosphate through brevibacillus brevis and application thereof

Abstract: The invention discloses a method for degrading triphenyl phosphate through brevibacillus brevis and application thereof and belongs to the technical field of environment organic pollutant biotreatment. The method specifically comprises the steps that a degradation culture medium with triphenyl phosphate as a unique carbon source is inoculated with the brevibacillus brevis under the condition that the temperature is 30 DEG C; five days after degradation of a constant-temperature shaking table, the concentration of the triphenyl phosphate left in the culture medium is measured through a gas chromatography-mass spectrometer (GC-MS), and in this way, the degrading effect of the brevibacillus brevis on the triphenyl phosphate is analyzed. According to the method, environment suitability of the method is high, and the cost is low; the degradation rate of organophosphorus fire retardant can reach 95.4% five days later. The actual application value is high, and a reference is provided for solving the problem of water organophosphorus fire retardant pollution treatment.

Brominated polyphenylene oxide and flame retardant employing the brominated polyphenylene oxide

Abstract: A brominated polyphenylene oxide having a molecular skeleton obtained by condensing tribromophenols and satisfying the requirements: (A) its 20 wt. % solution in chloroform has an absorbance at 600 nm of not larger than 0.6; (B) when 50 ml of ion-exchanged water is added to its 1.00 g/30 ml solution in dioxane, the resulting solution has an electroconductivity of not larger than 10 μS/cm measured at 25° C.; and (C) when a mixture comprised of 20% by weight of the brominated polyphenylene oxide and 80% by weight of triphenyl phosphate is heated at 280° C. for 20 minutes, the halide ion increase therein is not larger than 10 μmols per gram of the brominated polyphenylene oxide, is used as a flame retardant. When it is added to resin, the resin moldings are excellent in its flame retardancy, electric properties, physical properties, thermal stability and appearance (color hue), and they do not corrode molds.
