Mixture of Sodium Hydroxides and Sodium Phosphates as Beater Additives for Paper Strength Enhancement 苛性钠和磷酸钠(E339)作为打浆助剂提高纸张强度的作用
The ultraviolet absorption and emission spectra of Ce3 + doped phosphate glasses based on gadolinium and sodium phosphates are studied in the present work. 研究了基于钆和钠磷酸盐Ce3+掺杂磷酸盐玻璃的紫外吸收和发射光谱。
Production of Purified Sodium Phosphates by means of Melamine as Medium 反应媒循环法生产纯净磷酸钠(E339)盐的研究
Sodium, potassium and chloride, along with phosphates and bicarbonates, function to maintain homeostasis. 钠、钾和氯与磷酸盐、碳酸氢盐在一起,起着维持体内稳衡的作用。
Examples : sodium chloride ( common salt ); carbonates, sulphates and phosphates of sodium, potassium, and magnesium; besides calcium phosphates and iron. 如:氯化钠(盐)由钠、、组成的碳酸盐、酸盐、酸盐,及磷酸钙和铁等。
