Sodium alginate-based loaded nano-pyrophanite/lignite-based active coke hydrogel and preparation method thereof

The invention belongs to the field of adsorption-photodegradation water treatment, and discloses a sodium alginate-based loaded nano-pyrophanite/lignite-based active coke hydrogel and a preparation method thereof. According to the preparation method, the hydrogel is prepared from loaded nano manganese titanate/lignite-based active coke powder under the crosslinking action of sodium alginate, so that hydrophilic and hydrophobic refractory organic pollutants can be removed at the same time by using the surface characteristics of the hydrogel; the preparation process is simple and feasible; the granularity of the prepared hydrogel can be controlled, so that the hydrogel can be conveniently recovered from a liquid phase, the effluent quality is improved, and the use cost is low; the in-situ regeneration can be quickly realized, and the repeated use stability is good; and no toxicity is caused, and no secondary pollution is caused to the environment. 本发明属于吸附-光降解水处理领域，公开了一种基于海藻酸钠的负载纳米红钛锰矿/褐煤基活性焦水凝胶及其制备方法。本发明利用海藻酸钠的
