ABSTRACT

Lignin sulfonate, a by-product of pulp or fiber pulp production using the sulfite method, is directly extracted in its paper mill waste red liquor and is a non-toxic resource with a wide range of sources, low cost and renewable.In this paper, we combined nanotechnology with low-cost and abundant sodium lignosulfonate to prepare nano-sodium lignosulfonate preparation by nanotechnology, so as to improve its adsorption of zinc ions, and to study and investigate the effects of nano- and non-nano-sodium lignosulfonate treatment solution after adsorption of zinc ions on seedlings of wheat and mung beans by measuring the morphological and physiological and biochemical indexes of seedling growth and development. It will provide technical support for the treatment of heavy metal pollution in water environment and the agricultural application of treatment solution for zinc pollution, as well as the prevention of secondary pollution in water bodies after heavy metal treatment.The main research works are: (1) preparation of nano-sodium lignosulfonate formulations, focusing on the mass ratio of sodium lignosulfonate and sodium tripolyphosphate (STPP), magnetic stirring time, ultrasonic shaking time, pH value of the reaction system, and selection of suitable temperature; (2) characterization of the morphological structure of nano-sodium lignosulfonate formulations by laser pens, scanning electron microscopy, and optical microscopy; (3) The adsorption performance of nano-sodium lignosulfonate formulations on Zn²⁺ was studied, and the adsorption performance and effect of nano- and non-nano-sodium lignosulfonate formulations on Zn²⁺ were compared and observed.
