preparation example Construction
[0025] The present invention provides a kind of preparation method of thallium adsorbent, it comprises the following steps:
[0026] S10, taking the polyamide material for column chromatography and adding it to the dilute hydrochloric acid solution, mixing and soaking at room temperature for 20-24 hours;
[0027] In actual operation, polyamide materials can be washed with water to remove dust and powder, and block or granular materials can be selected. Preferably, the polyamide substance is polyamide resin or polyamide fiber.
[0028] S20, adding potassium ferrocyanide into the solution system in step S10, stirring evenly and standing for 20-24 hours before filtering;
[0029] It should be noted that the filtered filtrate can be reused after being supplemented with hydrochloric acid and potassium ferrocyanide as appropriate.
[0030] S30, take the filtered solid matter, add it to the ferric chloride solution, a blue precipitate appears on the solid matter, stir for 40-60 min...
Embodiment 1
[0046]S10, take 14-30 mesh polyamide resin for column chromatography, add 0.5mol / L HCl solution at room temperature according to 1:20 (weight ratio), and soak for 20 hours.
[0047] S20, adding potassium ferrocyanide to the solution system in step S10 so that the concentration of the potassium ferrocyanide solution is 0.1 mol / L, stirring evenly, soaking for 24 hours and then filtering.
[0048] S30, take the filtered polyamide particles, add 0.01mol / LFeCl according to 1:20 (mass ratio) 3 In the solution, a blue precipitate appeared on the polyamide particles, and continued to stir at a slow speed for 60 minutes until the blue precipitate no longer increased.
[0049] S40, filtering and washing with water to obtain a wet state thallium adsorbent.
Embodiment 2
[0051] S10, take 14-30 mesh polyamide fiber for column chromatography, add it into 0.5mol / L HCl solution at room temperature according to 1:20 (weight ratio), and soak for 23 hours.
[0052] S20, adding potassium ferrocyanide to the solution system in step S10 so that the concentration of the potassium ferrocyanide solution is 0.1 mol / L, stirring evenly, and filtering after standing for 20 hours.
[0053] S30, take the filtered polyamide fiber, add 0.01mol / LFeCl according to 1:20 (mass ratio) 3 In the solution, a blue precipitate appeared on the polyamide fiber, and continued to stir at a slow speed for 50 minutes until the blue precipitate no longer increased.
[0054] S40, filtering and washing with water to obtain a wet state thallium adsorbent.
