It was observed that a super-efficient gel adsorbent system (RRQG@CDC) could be obtained when a matrix material of polyquaternium gel with a flat distribution (RRQG) was loaded onto a skeleton material of cyclodextrin carbide (CDC). The results showed that the adsorption capacity of RRQG@CDC towards dyes was 1250 times higher than that of commonly used activated carbon, enabling highly efficient purification of dyeing wastewater through superior adsorption. In addition, RRQG@CDC demonstrated adaptability to a range of different pH values and salinity conditions, showing super-efficient adsorption abilities towards various types of dyes. Moreover, simulated scale-up tests confirmed the feasibility of this super-efficient adsorbent for practical engineering applications. An enhanced quasi-planar electrostatic adsorption mechanism model was established, which has changed the traditional understanding of adsorption mechanisms. Furthermore, the waste residues of RRQG@CDC, after dye adsorption, can be directly utilized as high-calorific fuels, showcasing the resourcefulness of these residues while eliminating the risk of secondary pollution. In conclusion, this study achieved a remarkably efficient and resource-based purification of dyeing wastewater by developing a highly effective adsorbent system.
