The present invention discloses a preparation method of corn stalk regenerated cellulose and nano activated carbon composite gel film, including: stripping air-dried corn stalks, cutting, grinding, screening to obtain shanks and leaves, and subjecting the shanks to oxygen, hydrogen peroxide, potassium hydroxide or anthraquinone treatment to obtain corn stalk cellulose; dissolving the cellulose by means of low-temperature lithium hydroxide (sodium hydroxide) or thiourea (urea) method; converting corn leaves into nano activated carbon by means of thermal carbonization, ball milling, ethanol activating and dispersing as well as centrifugal classifying; mixing the activated carbon with the stalk cellulose dissolved solution, shaping in a mold, neutralizing and shaping by sulfuric acid bath, washing, and drying to obtain the core stalk composite gel film. The gel film produced by the method is semitransparent and brown sheeting that has great ability to adsorb heavy metal ions such as Zn2+, Fe3+, Cd3+ and Cu2+.
