The invention discloses a device for preparing phosphate-free activated charcoal. The device can be used for preparing phosphate-free activated charcoal powder which has the advantages of no phosphate, strong adsorbability and even texture. The method for preparing the phosphate-free activated charcoal comprises the following steps of: preprocessing phosphorous activated charcoal; leaching the phosphorous activated charcoal to obtain the phosphate-free activated charcoal; and finally, inspecting the phosphate-free activated charcoal. The method disclosed by the invention can be used for obtaining high-efficiency and high-quality phosphate-free activated charcoal powder required for phosphorus measurement in agricultural detection, thereby saving a large amount of water resources and time, and greatly improving the leaching efficiency.
Description
technical field [0001] The invention relates to a device and method for making phosphorus-free activated carbon. Background technique [0002] Activated carbon is a very important industrial product with a wide range of uses, and activated carbon with special properties is used in agricultural inspections. The determination of available phosphorus in the national soil testing formula project will use a large amount of phosphorus-free activated carbon powder. At present, there is a lack of a device and method for making phosphorus-free activated carbon in the market. Most of the existing phosphorus-free activated carbon products are washed by researchers themselves. Due to improper washing methods, the washing efficiency is low, and a lot of time and water resources are wasted. Contents of the invention [0003] On the purpose of the present invention, research out a kind of device and the method for making phosphorus-free activated carbon. [0004] What the present inven...
