In order to determine the transformation process of high valence iron into zero valence iron at high temperatures, the TGA curves were obtained on a thermogravimetric analyzer at a heating rate of 20 °C·min−1. The effect of the preparation temperature (600, 800, and 1000 °C) on the reaction of carbon-reduced iron was analyzed (Fig. 1a, b, and c). The equilibrium composition diagrams at different temperatures were given in Fig. S1. The TGA and DTG results showed that there were various reaction

Nano zero-valent iron (NZVI) technology has shown good potential for the treatment of selenium in wastewater. In this study, NZVI was loaded on activated carbon (AC) by carbothermal reduction method to synthesize highefficiency adsorbent (NZVI@AC). The agglomeration of NZVI was suppressed and its reactivity was improved. The optimum preparation temperature of NZVI@AC (600 degrees C) was determined by comparing its purity. Moreover, the synergistic effect between the active component (NZVI) and the support (AC) was investigated on the basis of the density functional theory method. The smaller H...
