ABSTRACT

Nanotechnology can effectively improve the environmental hazards caused by petrochemical industry, so it is widely used in environmental protection field. Among them, the pollution of heavy metal Zn accounts for a larger proportion and the pollution degree is deeper.The investigation of heavy metal pollution in some bay area water shows that there are other heavy metals besides Zn in the estuary.Mining non-ferrous metal smelting, electroplating wastewater and some chemical enterprises discharged from the wastewater contains a large amount of zinc.With the rapid development of industry, the wastewater discharged into the environment by tannery, electroplating and zinc salt production has produced far-reaching zinc pollution to the environment. Therefore, the treatment of zinc-containing wastewater has received strong attention nowadays.Ligninsulfonate, 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, nano-sodium lignosulfonate was prepared by combining low-cost and abundant lignosulfonate to improve its adsorption capacity of zinc ions.The effects of nano-sodium lignosulfonate and non-nano-sodium lignosulfonate on the growth and development of mung bean seedlings after adsorbing zinc ions were studied by measuring the morphology and physiological and biochemical indexes of mung bean seedlings.The research will provide technical support for the treatment of heavy metal pollution in water environment, the agricultural application of zinc pollution treatment solution, and the prevention of secondary pollution after heavy metal treatment in water.The main research works were (1) preparation of nano-sodium lignosulfonate formulations; (2) characterization of morphological structure of nano-sodium lignosulfonate formulations by laser pointer, scanning electron microscope and optical microscope; (3) treatment solution with nano- and non-nano-sodium lignosulfonate formulations adsorbed with Zn2+, treatment of mung bean seeds, and study of its effect on wheat germination and seedling growth under Zn ion stress .The results showed that (1) the prepared nano-adsorbents exhibited homogeneous fine granularity and uniform dispersion with particle size in the range of about 20 nm to 60 nm under room temperature neutral conditions; (2) the adsorption of the nano-formulations was higher than that of the non-nanoproducts under the same conditions. (3) The effect of nano-sodium lignin sulfonate was found to be better than that of non-nanopreparations for the alleviation of Zn stress by seedling trials in wheat, and the best effect was obtained when the addition amount was 30 ml.
