To provide a porous molding that can be used as a molding that has sufficient strength to be self-supportable even when the dimensions change due to absorbing water and that can be suitably used as a filter for removing impurities in a liquid or gas. A porous molding is achieved by sintering a mixed powder including a dried gel powder and a thermoplastic resin powder, wherein the ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder d.sub.2/d.sub.1 is 1.3 or greater, and the difference ratio of average particle diameter d.sub.1 of the thermoplastic resin powder to the average particle diameter d.sub.2 of the dried gel powder and the average particle diameter d.sub.3 of the dried gel powder when absorbing water and swelling is (d.sub.3d.sub.2)/d.sub.1 is 4.0 or less.

A treated wine beverage prepared by a process including exposing a pretreated wine beverage to an ion exchange matrix. The ion exchange matrix includes a mixture of cation exchange media and anion exchange media that includes: (1) cation exchange media that are in hydrogen form, (2) cation exchange media that are in mineral form comprising potassium mineral form, (3) anion exchange media that are in hydroxide form, and (4) anion exchange media that are in chloride mineral form. The exposing results in: binding ions of the mixture to one or more cationic or anionic constituents present in the pretreated wine, reducing concentrations of the one or more cationic or anionic constituents in the wine and maintaining a conductivity value of the treated wine equal to or greater than the pretreated wine beverage's conductivity value.

An ion exchange tank is provided. The ion exchange tank includes a processing chamber and an additive chamber separated by a weir system, the weir system having a flow channel fluidly connecting the processing chamber to the additive chamber, wherein the flow is divided from the additive chamber by a first partition and divided from the processing chamber by a second partition, wherein the additive chamber comprises a solids-absorbing material disposed therein.

Disclosed is a PLGlu-SS-lithium ion-sieve composite, preparation method and use thereof. The PLGlu-SS-lithium ion-sieve composite includes an H.sub.3LiMnTi.sub.4O.sub.12 lithium ion-sieve and poly--glutamic acid (-PGA) compounded with the H.sub.3LiMnTi.sub.4O.sub.12 lithium ion-sieve, where a terminal amino group of the -PGA is linked to a disulfide bond-containing group. In the present disclosure, the H.sub.3LiMnTi.sub.4O.sub.12 lithium ion-sieve is used as a support structure with sufficient strength support, high structural stability, and excellent cycling performance; the pores and surface of the H.sub.3LiMnTi.sub.4O.sub.12 lithium ion-sieve both are bonded with PLGlu-SS. At a low pH, PLGlu-SS is protonated and folded to form-helix, and at a high pH, PLGlu-SS is deprotonated and extended. Thus, under alkaline adsorption and acidic desorption, a pore size of the composite can be adjusted to provide large adsorption capacity, high adsorption selectivity, and high adsorption efficiency. Therefore, the composite is an efficient lithium ion adsorption material with high adsorption capacity and high stability.
