This invention relates to a method for preparing and using a biopolymer chitosan-modified magnetic sepiolite adsorbent. First, sepiolite (Sep) is co-precipitated with a magnetic core (Fe3O4) to magnetically modify it, yielding magnetic sepiolite (MSep). Then, chitosan (CTS) is extensively cross-linked onto the MSep surface using glutaraldehyde as a cross-linking agent, preparing a functionalized magnetic solid adsorbent (MSep@CTS) with a complete core-shell structure and abundant adsorption sites. Importantly, this material exhibits excellent adsorption performance for antimony ions and synergistic adsorption capacity for both Sb(III) and Sb(V) co-occurring in water. This "easy to obtain, easy to prepare, highly efficient, and clean" characteristic provides significant economic advantages and sustainable development potential while achieving high-performance adsorption, laying a solid foundation for large-scale practical applications.

This invention provides a circumferential support structure to improve the overall rigidity of the stator foundation. The circumferential support structure is arranged circumferentially between two adjacent stator foundation piers, and it passes through the inner side of the ventilation channel between the two stator foundation piers in a sealed manner. This invention features a compact structure. While ensuring the ventilation channel is adequately utilized, a circumferential support beam is installed between two adjacent stator foundation piers, connecting the circumferentially spaced stator foundation piers into a unified whole. This invention not only guarantees the required area of ​​the ventilation channel within the stator foundation but also improves the overall rigidity of the stator foundation, especially the circumferential rigidity of the structure. This is beneficial for improving the overall structural integrity and load-bearing capacity of the stator foundation, reducing unit vibration effects, and enhancing the safety of the stator foundation. This invention has a wide range of applications and significant technical and economic advantages.

The problem addressed by the invention described in claim 1 is that of reducing the energy consumption of electrical systems to the minimum required value depending on the operating conditions, without having to make changes to the existing system structure. The method and the device for reducing the energy consumption of existing electrically operated systems containing consumers whose power feed from a network (#1A) is controlled in each case via control modules are characterized in that the power is supplied to the control modules of the existing system via a control device according to the invention having a power supply (#1B) that is independent of the network (#1A) and in that all relevant operating parameters of the consumers of the existing system are updated in the control modules of the existing system and are maintained in the event of the consumers of the existing system losing power. The device according to the invention is thus used to achieve considerable economic advantages by virtue of reducing the energy consumption of existing electrical systems with minimal changes to the existing systems.
