    摘要: A process for separating the isomers of dichlorobenzene from a feed mixture of the same. Separation of the isomers is effected by selective absorption and desorption and is susceptible to various flow schemes for performing continuous adsorptive separations. The process uses an X-type zeolite adsorbent having a mixture of sodium and potassium ions in the exchangeable cationic sites. The desorbent may be an alkyl benzene, such as toluene, xylene, p-diethylbenzene, etc.

    摘要: A process for the removal of toxic cations and anions from gastrointestinal fluids is disclosed. A pH-increasing medication is administered prior to or together with a microporous cation exchanger. An additional feature of the invention is the use of a proton form of the microporous cation exchanger. The acidity of the gastrointestinal fluids is decreased to improve the stability of the microporous cation exchangers, which are represented by the empirical formula: ApMxZr1-xSinGeyOm  (I) or ApMxTi1-xSinGeyOm  (II)
