Chemicals used for treatment of water intended for human consumption - sodium calcium polyphosphate ; german version en 1208 : 2005 人类生活用水处理用化学制品.聚磷酸钠钙
Metachromatic granules contain rna and polyphosphates they are deeply stained with aniline dyes 。 they are characteristic features of the corynebacteria 异染颗粒含rna和多聚磷酸盐。用苯胺染料可浓染。是棒状杆菌的特点。
The most widely used ones are caustic soda , silicates ( especially sodium metasilicate , which is a very powerful emulsifier ) , trisodium phosphate ( the well - known tsp ) , sodium polyphosphates and sodium bicarbonate 使用最广的有氢氧化钠、硅酸盐(特别是偏硅酸钠,是一种强有力的乳化剂) 、磷酸三钠(著名的tsp ) 、多磷酸钠及碳酸氢钠。

Amp and adp were not significantly changed throughout the experiments , pa tended to decreased with the increases of concentrations of pollutants , nitrite - na and sodium polyphosphate could decrease atp , while methyl parathion showed a disordered atp change . aec , atp / adp and total adenylate content solely could be poor health condition markers . pa and atp are proposed as direct health condition markers of an organism to environmental stress 整个实验中未发现腺苷一磷酸( amp )和腺苷二磷酸( adp )有显著变化,磷酸精氨酸随着化合物浓度升高呈下降趋势,亚硝酸钠和多聚磷酸钠能引起腺苷三磷酸( atp )下降,而甲基对硫磷中atp变化混乱。
Triphosphates are salts or esters of polymeric oxyanions formed from tetrahedral PO4 (phosphate) structural units linked together by sharing oxygen atoms. When two corners are shared the polyphosphate may have a linear chain structure or a cyclic ring structure.
