摘要: There has been a surge in usage of biotherapeutic products in multiple industries. The biotherapeutic products are a mixture of their charge variants which are separated by a continuous chromatography process. This disclosure provides a method and an apparatus for control and optimization of the continuous chromatography process. The present disclosure helps controlling composition of charge variants in biotherapeutic products by developing an apparatus that has unique architecture including advanced Distributed Control System (DCS), programmable logic controllers (PLCs), Local area network (LAN) setup and Python layer with user interface. This allows an operator to monitor charge variant concentrations and obtain an optimal schedule to implement such that a target product composition is achieved. The present disclosure comprises a data-pre-processing step followed by prediction of process parameters using soft sensor and prediction models. The chromatography process is optimized to achieve targeted purity and yield by recommending optimal values of manipulated variables.

摘要: Rare earth elements (REEs) play an essential role in our modern society, being critical resources for the growing electronic devices and renewable energy technologies. For the reversible capture and release of REEs, we designed and synthesized a redox-copolymer poly(ferrocenylpropyl methacrylamide-co-methacrylic acid) (P(FPMAm-co-MAA)) that combines an ion-exchange carboxylic acid group for REE adsorption, and an redox-active ferrocene moiety for electrochemical regeneration. By molecularly tuning the copolymer composition, efficient adsorption uptake could be achieved alongside electrochemically regenerated adsorbent reuse. The copolymer sorbent showed stoichiometric binding for yttrium (Y), cerium (Ce), neodymium (Nd), europium (Eu), gadolinium (Gd), and dysprosium (Dy) based on carboxylic acid active site.

摘要: A method of radionuclide waste extraction includes directing a waste stream from an upstream segment of a main waste pathway into a waste stream input of an anion exchange column, wherein the waste stream comprises uranium and a target radionuclide, the anion exchange column houses an anion exchange resin, a cation exchange column housing a cation exchange resin is fluidly coupled to the anion exchange column downstream the anion exchange column, and a sluicing preparation tank is fluidly coupled to the anion exchange column. The method further includes adsorbing uranium from the waste stream onto an anion exchange resin, directing the waste stream from the anion exchange column into the cation exchange column, adsorbing the radionuclide onto the cation exchange resin, removing spent anion exchange resin from the anion exchange column, and directing fresh anion exchange resin from the sluicing preparation tank into the anion exchange column.

摘要: A process for removing Pb2+ toxins from bodily fluids involves contacting the bodily fluid with an ion exchange composition to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchange composition. The ion exchange compositions are represented by the following empirical formula:
AmTiaNb1-aSixOy
having either the pharmacosiderite, sitinakite, pharmacosiderite-sitinakite intergrowth topologies or mixtures thereof. There are also compositions comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.-

摘要: A structured organic film (SOF) is disclosed. The structured organic film also includes a plurality of segments, a plurality of linkers, and optionally a plurality of capping segments, where at least one or more capping segments may include at least one cationic species. Implementations of the structured organic film (SOF) include where all of the plurality of linkers are bonded to the plurality of segments. A concentration of ionic capping segments in the SOF is from about 0.1 to about 5.0 molar equivalents of ionic capping segments as compared to a concentration of nonionic segments in the SOF. An ion-exchange membrane may include the structured organic film (SOF).

摘要: Provided are an apparatus and a method for ion-exchange extraction of lithium from natural or technological brine by using a lithium-selective inorganic sorbent operating on a principle of an ion sieve. The apparatus contains a plurality of ion-exchange columns arranged and interconnected in sequence. Flows of the brine, flush water, acidic desorption solution, and outputs, of the processed products are controlled via switchable shut-off valves. The method can be carried out by operating the apparatus in a parallel or a serial mode of column operations. In the parallel mode, all columns work simultaneously in the same manner. In the serial mode of operation, the columns work individually with a shift of the sorption-flushing-desorption-flushing cycles sequentially and with a transfer of the processed brined sequentially from the first column to the last column and from the last column to the first one thus providing continuity of the lithium-extraction process.
