Embodiment 1
[0019] A snakeskin bag containing 20kg of attapulgite, whose overall thickness is controlled at 30cm, is irradiated by high-energy electron beams with an energy of 10MeV and a dose of 40keV for 30 seconds and 50 seconds respectively. Then, according to the mass ratio of 20%, it is added to the solid pesticide chlorpyrifos to make a wettable powder, which is a controllable loss pesticide.
Embodiment 2
[0021] A snakeskin bag containing 10kg of attapulgite, whose overall thickness is controlled at 30cm, was irradiated with high-energy electron beams with an energy of 10MeV and a dose of 30keV for 30 seconds and 80 seconds, respectively. Then as an adsorbent, absorb heavy metal (chromium ion) wastewater at a concentration of 1g / L, and the concentration of chromium ion after attapulgite adsorption is 0.1g / L.
Embodiment 3
[0023] A snakeskin bag filled with 30kg of diatomite, whose overall thickness is controlled at 30cm, is irradiated with high-energy electron beams with an energy of 15MeV and a dose of 40keV for 30 seconds and 50 seconds respectively. Then, as a pesticide attachment aid, it is added to the liquid pesticide chlorpyrifos at a mass ratio of 10% to make a suspension, which is a controllable loss pesticide.
