Ensuring that the concentration of treated wastewater reaches the allowable concentration according to Vietnamese standards on industrial wastewater also plays an important role in eliminating the explosive properties of these explosive components. Table 1.3. Characteristics and composition of ...
Independent of pH (except Cr (VI)). Normally, an increase in pH will promote the photoreduction of metal ions. However, photogenerated electrons not only participate in the photoreduction reaction of metal ions but they can also reduce protons, water and dissolved oxygen depending on specific ...
The titanium in this region is mainly concentrated along the coast of Ninh Thuan. Of the more than 10 mines and titanium mineral deposits in this region, 3 have been explored and their reserves have been assessed; these are the Chum Gang, Bau Doi and Go Dinh mineral deposits. The reserves of the 3 ...
B. Effect of temperature To evaluate the effect of temperature, we conducted hydrothermal treatment of precursor solution (with Ti and Fe concentrations of 2.46 g/L and 0.57 g/L, respectively), solution pH was 5, GNP content used was 20 mg, at different temperatures including 100 o C, 120 o C, 150 ...
