Embodiment 1
[0023] First add 30g of MnO2 solid into a 100mL crucible, then add 10.41g of LiCl·H2O, mix well, add 10mL of deionized water, heat to 50°C on an electric furnace, and stir for 1h. Put the crucible into the muffle furnace, set the temperature at 200°C, calcinate for 3 hours, take out the crucible after 3 hours, and crush the solid adsorbent to obtain the precursor LiMn2O4. According to the proportion of the sponge formula, the powdered adsorbent with a mass fraction of 10% is added, mixed and foamed with the sponge foaming raw material, and the foamed sponge adsorbent is obtained. Use 0.1mol / L hydrochloric acid to carry out pickling for 0.5h, and the pickling rate reaches 75%. The sponge after pickling is put into brine for adsorption experiment, and the adsorption capacity is 2.5mg / g as determined by flame photometer.
Embodiment 2
[0025] First add 30g of MnO2 solid to a 100mL crucible, weigh 9.37g of LiCl H2O and dissolve it in 20mL of water, add the lithium chloride solution to the crucible and mix it with manganese dioxide, then place the crucible on an electric furnace and heat it to 80°C, stirring for 0.5 h. Put the crucible into the muffle furnace, set the temperature at 500°C, calcinate for 2 hours, take out the crucible after 2 hours, and crush the solid adsorbent to obtain the precursor LiMn2O4. According to the proportion of the sponge formula, the powdered adsorbent with a mass fraction of 20% is added, mixed and foamed with the sponge foaming raw material, and the foamed sponge adsorbent is obtained. 0.2mol / L hydrochloric acid was used for pickling for 0.5h, and the pickling rate reached 80%. The sponge after pickling was put into brine for adsorption experiment, and the adsorption amount was 2.6mg / g as determined by flame photometer.
Embodiment 3
[0027] First, add 30g of MnO2 solid to a 100mL crucible, weigh 12.49g of LiCl H2O and dissolve it in 20mL of water, add the lithium chloride solution to the crucible and mix it with manganese dioxide, then place the crucible on an electric furnace and heat it to 90°C, stirring for 0.5 h. Put the crucible into the muffle furnace, set the temperature at 800°C, calcinate for 1 hour, take out the crucible after 1 hour, and crush the solid adsorbent to obtain the precursor LiMn2O4. According to the proportion of the sponge formula, the powdered adsorbent with a mass fraction of 40% is added, mixed and foamed with the sponge foaming raw material, and the foamed sponge adsorbent is obtained. 0.2mol / L hydrochloric acid was used for pickling for 0.5h, and the pickling rate reached 81%. The sponge after pickling was put into brine for adsorption experiment, and the adsorption amount was 2.8mg / g as determined by flame photometer.
