99% Sodium Tungstate 359

99% sodium tungstate’s impurities may be determined using lanthanum hydroxide as coprecipitation agent by inductively coupled plasma atomic emission spectrometry (ICP-AES method) after coprecipitation separation and concentration of these impurities. These trace metal impurities are calcium, tin, cobalt, copper, iron, manganese, zinc, and nickel, etc. The determination of trace metal impurities must be performed on a high resolution spectrometer if the ICP-AES method is adopted directly. That is because the matrix tungsten often has severe spectral overlap interference with the…

Fe-doped Tungstic Acid 595

Fe-doped tungstic acid may be prepared using sodium tungstate and iron salts as materials. Since Fe initiates the Fenton reaction, the photocatalytic activity of tungstic acid is greatly improved. Also, this is a heterogeneous reaction that avoids the loss of iron ions and thus enables the reuse of the catalyst. Tungsten compounds have a wide range of applications in the field of photocatalysis. These compounds can undergo intramolecular charge transfer under the irradiation of ultraviolet light, thereby triggering the degradation…
