Embodiment 1
[0044] A kind of preparation method of the soil water-retaining agent that utilizes aluminum ash to produce, comprises the following steps (can refer to Figure 5 shown):
[0045] (1) The aluminum ash after the aluminum extraction is mixed with the nitric acid solution with a concentration of 0.1mol / L, the mass volume ratio of the aluminum ash after the aluminum extraction and the nitric acid solution is 1:1g / mL, and the stirring process (rotating speed is 50rpm, time is 10min), then ultrasonic treatment (ultrasonic time is 30min), shaker shakes and disperses evenly (rotating speed is 100r / min, time is 10min), stands still (standstill time is 1h), vacuum suction filtration for the first time, obtains The first filtrate and the first filter residue;
[0046] (2) adding 100mL concentration to the filtrate for the first time described in step (1) is the sodium sulfide solution of 0.1mol / L, the volume ratio of the filtrate and sodium sulfide solution for the first time is 1:1, mi...
Embodiment 2
[0052] A kind of preparation method of the soil water-retaining agent that utilizes aluminum ash to produce, comprises the steps:
[0053] (1) the aluminum ash after the aluminum extraction is mixed with a concentration of 0.3mol / L nitric acid solution, the mass volume ratio of the aluminum ash after the aluminum extraction and the nitric acid solution is 1:5g / mL, and the stirring process (rotating speed is 100rpm, Time is 30min), then ultrasonic treatment (ultrasonic time is 30min), shaker shakes and disperses evenly (rotating speed is 150r / min, time is 10min), stands still (standstill time is 5h), vacuum suction filtration for the first time, obtains The first filtrate and the first filter residue;
[0054] (2) adding 100mL concentration to the filtrate for the first time described in step (1) is the sodium sulfide solution of 1.0mol / L, the volume ratio of the filtrate and sodium sulfide solution for the first time is 1:2, mix uniformly to obtain Mixed solution, leave stand...
Embodiment 3
[0060] A kind of preparation method of the soil water-retaining agent that utilizes aluminum ash to produce, comprises the steps:
[0061] (1) the aluminum ash after the aluminum extraction is mixed with the nitric acid solution with a concentration of 0.5mol / L, the mass volume ratio of the aluminum ash after the aluminum extraction and the nitric acid solution is 1:10g / mL, and the stirring process (rotating speed is 100rpm, time is 20min), then ultrasonic treatment (ultrasonic time is 30min), shaker shakes and disperses evenly (rotating speed is 100r / min, time is 30min), stands still (standstill time is 5h), vacuum suction filtration for the first time, obtains The first filtrate and the first filter residue;
[0062] (2) adding 100mL concentration to the filtrate for the first time described in step (1) is the sodium sulfide solution of 5.0mol / L, the volume ratio of the filtrate and sodium sulfide solution for the first time is 1:10, mix uniformly to obtain Mixed solution, ...
