The invention discloses a structure self-growing aqueous phase phosphate radical adsorbing material and a preparation method and application thereof. The preparation method comprises the following steps: adding clay to pre-sintered egg shell powder, ball-milling and mixing, pelleting, staling, molding, sintering, cooking and drying to obtain the structure self-growing aqueous phase phosphate radical adsorbing material. The problem that the conventional adsorbent cannot avoid adsorption saturation is solved from mechanism, the new breakthrough of the adsorption mechanism is realized, waste resources such as diatomite, silica powder produced by an iron alloy smelting plant and oyster in the farm produce fair are used as raw material to develop the structure self-growing aqueous phase phosphate radical adsorbing material, the phosphate radical ions in the sewage are effectively adsorbed, the problem of egg shell powder pollution is solved while solving the problem of phosphorous-enriched water pollution; the preparation method of the material is simple and effective, low in cost, easy to popularize, and has good economic benefit and environment benefit; and the material can be well put into scale production to promote the sustainable development of the social economy and environment.

The invention discloses a method for preparing a polyphenylene-sulfide-based strongly acidic ion exchange fiber. The method comprises the following steps of: fully swelling a polyphenylene sulfide fiber serving as a raw material in an organic solvent; adding a coupling agent and a catalyst into the polyphenylene sulfide fiber after the polyphenylene sulfide fiber is swelled; under the action of no stirring, raising the temperature of a reaction solution of the polyphenylene sulfide fiber for coupling reaction; after the reaction is finished, washing an obtained product, and performing acid boiling, extraction and drying treatment sequentially so as to obtain a coupled polyphenylene sulfide fiber; fully swelling the obtained coupled polyphenylene sulfide fiber in the organic solvent, adding a sulphonated reagent after the coupled polyphenylene sulfide fiber is swelled; under the action of no stirring, raising the temperature of the reaction solution for sulphonation reaction; after thereaction is finished, washing an obtained product and performing extraction and drying treatment sequentially, and treating to obtain the polyphenylene-sulfide-based strongly acidic ion exchange fiber. The polyphenylene sulfide fiber serving as the raw material has low cost and is readily available; compared with the prior art, the method has the advantage of obviously reducing the production cost; furthermore, in the preparation method, a radiation grafting technology is avoided totally, and the process is simple and easy to operate.
