The glass-forming region in the system Li 3PO 4–Pb 3(PO 4) 2–BiPO 4 (Li 2O–PbO–Bi 2O 3–P 2O 5) was determined and a study of ionic conductivity of glasses belonging to this system was carried out. The ionic conductivity, σ, increases substantially with increasing con...
Phosphorus (P) is one of the most limiting factors for plant growth, development, and productivity in many natural and agricultural ecosystems. P is acquired by plants from the soil in the form of inorganic phosphate (Pi). Due to the high reactivity of Pi with cations present in the soil ...

By pulse radiolysis of aquenos solutions of H 3PO 4, H 2PO 4 -, HPO 4 2- and of P 2O 7 4- phosphate radicals formed by attack of OH, O aq - and H were found which have a characteristic absorption spectrum with one band in the visible region ( λ max = 500 nm for orthophosp...
Synthesis of NTP-NW/C and NTP-P/C First, 1 mmol Titanium (IV) oxide acetylacetonate (C10H14O5Ti) was slowly added into 20 mL iso-propyl alcohol and vigorously stirred for 1 h to obtain a pale-yellow solution. Then 0.18 mL H3PO4 was dropwise added into the above solution...
Compared to BU-TiO2-X, the peaks of the BU-TiO2-X/Ag3PO4 (3:1) sample showed a positive shift in binding energy, indicating an interfacial interaction between Ag3PO4 and BU-TiO2-X. This could be ascribed to the formation of Ti–O–P bonds, which were beneficial for reducing the ...
但是PO₄ 3-里面涉及到了P与O的配位键，形成配位键之后更加稳定，所以磷酸根是PO₄3-。磷酸根，化学式PO₄ 3-，各种磷酸根离子跟硝酸银反应生成的沉淀颜色不同，在硝酸中的溶解性不同，酸化后跟蛋白溶液的作用也不同。利用这些性质可以鉴别各种磷酸根离子。
TP,总磷。P当然是磷了。测试方法：水质 总磷的测定 钼酸铵分光光度法 Water quality－Determination of total phosphorus- Ammonium molybdate spectrophotometric method GB 11893-89 1 主题内容与适用范围 本标准规定了用过硫酸钾（或硝酸－高氯酸）为氧化剂，将未经过滤的水样消解，用钼酸铵分光光度测定...
The electrochemical properties of Na4Co3(PO4)2P2O7 as a positive electrode for sodium-ion batteries were characterized by a cyclic voltammetry technique and galvanostatic charge/discharge tests. Interestingly, Na4Co3(PO4)2P2O7 has the multi redox couples in the highest potential region between ...
Na4Fe3(PO4)2(P2O7)/C nanospheres were prepared with a template method using a nonionic triblock surfactant Pluronic-F127 (Mw = 12600, PEO106PPO70PEO106, Sigma-Aldrich) as the structure directing agent. Typically, 1.23 g of F127 was first dissolved in 20 mL of deionized water...
