The results showed with respect to Meretrix Linnaeus, the optimum was Sodium pyrophosphate(0.1%)、Sodium tripolyphosphate(0.1%)、sucrose(2%)、sorbite(3%);
The result showed that the storage time of pork could be prolonged at following treatment condition: sterilized with 1.5% H_2O_2, dipped short time in mixing preservative made from 1.0% citric acid, 0.3% Na_2EDTA, and 1.5% sodium tripolyphosphate, carbonating packed with NY/PE coextruded film.
It was shown that the coated phosphate can obviously enhance the magnetism of γ-Fe_2O_3 and the coating effect of phosphate is as follow: sodium metaphosphate>sodium tripolyphosphate>sodium pyrophosphate.
The results showed that addition 10% walnut dregs, 6% malt dextrin, 4% sugar, 4% non-dairy creamer, 6% de-fatted milk poder,0.4% sucrose esters of fatty acids (sucroesters; SE), 0.2% Sodium Tripolyphosphate in thick liquid, we can get high nutritivevalue walnut poder which contained 15% proteins after spraying and drying.
Conclusion: The use of a dentifrice containing 1% tetrasodium polyphosphate,7% sodium tripolyphosphate, 0.243% sodium fluoride and 10% high cleaning silica is effective in reducing natural extrinsic dental stain, when compared to a placebo fluoride dentifrice.
Among them, phosphoric acid, HEDP, and phosphoric acid solutions with ethylene glycol, sodium tripolyphosphate, and Cu oxide as additives produced the best electropolished surfaces (mean roughness: Ra>amp;lt;10 nm) on bulk Cu.
The SAS, judged from their efficiency for decreasing porosity, are arranged in ascending order: sodium silicate water glass, sodium tripolyphosphate, complex organomineral thinner, and FS-20 castament.
The authors of this paper have obtained the tetravalent terbium compound by oxidation of the corresponding trivalent speicies with ozone in alkali aqueous solution of sodium tripolyphosphate.The color of solution was changed from colorless to dark red-brawn after reaction. According tO the data of chemical analysis and absorption spectra it was confirmed for the formation of Tb(Ⅳ) in solution. The absorption band with the highest absorption at 365nm is considered to be one of the characterestics...
The disadvantages of traditional chelating agent sodium tripolyphosphate (STPP) from the point of view of ecosystem equilibrium and enviromental protection are analysed. The present situation of chelating agents research according to compound classification in introduced.
The influence of non—ionic surfactant Triton X-100 on the determination of lead by differential anodic stripping voltammetry was studied In 0.5 mol/L solution of hydrochloric acid containing 0.04%Triton X-100, the anodic stripping peak height of lead was increased. The sensitization by Triton X-100 occurs in the stripping step. The conditions for the simultaneous determination of trace copper and lead in sodium tripolyphosphate, a food additive, were studied.
