Embodiment 1
[0023] A heavy metal adsorption material prepared from corn stalks, made of the following raw materials in parts by weight: 13 parts of corn stalks, 21 parts of natural zeolite, 5 parts of oxalic acid, 3 parts of sodium edetate, and 1 part of bisabolone .
[0024] In the present embodiment, the preparation method of the heavy metal adsorption material prepared by using corn stalks, the steps are as follows:
[0025] 1) Weigh corn stalks, crush them to a particle size of 3mm, put them in an oven, and dry them at 125°C for 2 hours to obtain corn stalk powder;
[0026] 2) putting the corn stalk powder into a superfine pulverizer for superfine pulverization, and passing through a 500-mesh sieve after the superfine pulverization to obtain the corn stalk superfine powder;
[0027] 3) take natural zeolite by weighing, after pulverizing, cross 150 mesh sieves, obtain zeolite powder, set aside;
[0028] 4) Weigh oxalic acid, add 15 times the weight of deionized water, and stir until ...
