Embodiment 1
[0027] An adsorbent for heavy metal wastewater treatment, comprising the following raw materials in parts by weight: 100 parts of modified zeolite powder, 100 parts of modified attapulgite, 40 parts of hydrophilic modifier, 15 parts of sodium bicarbonate, aluminosilicate 100 parts of powder, 400 parts of water.
[0028] Further, the hydrophilic modifier is a polyether surfactant.
[0029] A preparation method for an adsorbent for heavy metal wastewater treatment, comprising the following steps:
[0030] Step 1. Preparation of modified zeolite powder. Take natural zeolite and grind it through a 100-mesh sieve to obtain zeolite powder. Put the zeolite powder in a muffle furnace, heat it to 600°C, and roast it at a constant temperature for 2 hours. Add 1mol / L hydrochloric acid to the roasted zeolite powder, the ratio of the volume of hydrochloric acid to the mass of zeolite powder is 1mL: 3g, stir evenly, put it under ultrasonic conditions for 30min, ultrasonic power is 600W, va...
Embodiment 2
[0036] An adsorbent for heavy metal wastewater treatment, comprising the following raw materials in parts by weight: 150 parts of modified zeolite powder, 75 parts of modified attapulgite, 45 parts of hydrophilic modifier, 10 parts of sodium bicarbonate, aluminosilicate 110 parts of powder, 450 parts of water.
[0037] Further, the hydrophilic modifier is a polyether surfactant.
[0038] A preparation method for an adsorbent for heavy metal wastewater treatment, comprising the following steps:
[0039] Step 1. Preparation of modified zeolite powder. Take natural zeolite and grind it through a 100-mesh sieve to obtain zeolite powder. Put the zeolite powder in a muffle furnace, heat it to 600°C, and roast it at a constant temperature for 2 hours. Add 0.1 mol / L hydrochloric acid to the calcined zeolite powder, the ratio of the volume of hydrochloric acid to the mass of zeolite powder is 1mL: 3g, stir evenly, put it under ultrasonic conditions for 30min, ultrasonic power is 600W,...
Embodiment 3
[0045] An adsorbent for heavy metal wastewater treatment, comprising the following raw materials in parts by weight: 150 parts of modified zeolite powder, 75 parts of modified attapulgite, 45 parts of hydrophilic modifier, 20 parts of sodium bicarbonate, aluminosilicate 110 parts of powder, 450 parts of water.
[0046] Further, the hydrophilic modifier is a polyether surfactant.
[0047] A preparation method for an adsorbent for heavy metal wastewater treatment, comprising the following steps:
[0048] Step 1. Preparation of modified zeolite powder. Take natural zeolite and grind it through a 100-mesh sieve to obtain zeolite powder. Put the zeolite powder in a muffle furnace, heat it to 600°C, and roast it at a constant temperature for 2 hours. Add 1mol / L hydrochloric acid to the roasted zeolite powder, the ratio of the volume of hydrochloric acid to the mass of zeolite powder is 1mL: 3g, stir evenly, put it under ultrasonic conditions for 30min, ultrasonic power is 600W, vac...
