Embodiment Construction
[0019] The preparation method of the modified liquid is to mix the sea mud and the acetic acid solution at a mass ratio of 1:5-7, stir and mix, filter, and collect the filtrate to obtain the modified liquid.
[0020] The additive is formed by mixing liposome and mesoporous nano silicon dioxide in a mass ratio of 4:2-4.
[0021] The surfactant is any one of sodium dodecylbenzenesulfonate and sodium lauryl sulfate.
[0022] The auxiliary agent is any one of ammonium bicarbonate and sodium bicarbonate.
[0023] A preparation method of a metal ion adsorbent, the preparation method comprising the steps of:
[0024] (1) Take the bamboo for crushing, pass through a 100-mesh sieve, collect the sieved particles, mix the sieved particles with the ethanol solution at a mass ratio of 1:4-6, and steam explode. The condition of steam explosion is 4.2-4.6MPa, and the pressure is maintained 100-130s, collect the steam explosion, filter, collect the filter residue, mix the filter residue wit...
