Embodiment 1
[0054] Calcium oxide and aluminum-silicon raw materials (mass ratios of calcium / silicon are 0.38, 0.45, 0.75, 0.80 respectively; Si / Al mass ratio is 1.7) are placed in a sodium hydroxide solution with a concentration of 0.5mol / L to obtain a slurry, wherein, The liquid-solid ratio is 15ml / g, and it is heated to 170°C in a closed container for hydrothermal reaction for 3 hours; followed by solid-liquid separation and drying to obtain the composite material.
[0055] The separated composite material was subjected to the heavy metal adsorption experiment, and the realization process was as follows: prepare a heavy metal ion solution with a concentration of 100mg / L with the nitrate of the corresponding metal to be tested, adjust the pH of the heavy metal ion solution to 4.5, and then mix the composite adsorbent according to 0.1 The dosage of g / L is added to the heavy metal ion solution, shaken in a constant temperature oscillator for 4 hours, and then taken out. The conditions of t...
