Synthesis of polyethenoxyether phosphate using polyethenoxyether as initiator and using phosphorus pentoxide as parkerizing reagent, and its application were studied.
The optimized conditions for phosphorus recovery as hydroxyapatite from wastewater by synthetic tobermorite through seeded crystallization were studied in this paper.
On the basis of acetone-phosphomolybdate method to detect phosphorus, the microplate method was developed for the determination of activity units of phytase.
The biodegradability of tapioca starch cross linked with phosphorus oxychloride was studied according to the half-vivo model by using micropopulation symbiotic cocultures.
Jolley(1993)is a study of dissolved phosphorus speciation in the lower molongolo sewage treatment plant(Canberra, Australia)detected no triphosphate in raw sewage entering the plant.
The water eutrophication is caused by the incessant accumulation of nitrogen and phosphorus in water and excessive propagation of a few of algal and hydrobios.
In this paper,the relation of heterotrophic bacteria to nitrogen and phosphorus in marine environment is studied by adding nitrogen and phosphorus to the seawater in mesocosm.
Coupling agent is used to microencapsulate red phosphorus.The DTA tests, friction sensitivity tests and hygroscopic tests have been used to evaluate the stability of red phosphorus.
The paper is a study of the rheologic character of phosphate di-starch which is using sodium trimetaphosphate and phosphorus oxycholride as crosslinking agent by rotating viscometer.
The method has been successfully used to the determination of phosphorus in ferronickel samples.The results compare favourably with determination values of compensating method with reference solution.
