  • Patent number: 9468866
    Abstract: Processes are provided which utilize fiber conduit reactors/contactors to effect extraction of metal element/s, metal compound/s, metalloid element/s, and/or metalloid compound/s from a fluid stream. In particular, methods are provided which include introducing a first stream comprising an extractant and a second stream comprising a metal element, a metal compound, a metalloid element, and/or a metalloid compound into a conduit reactor proximate a plurality of fibers. The second stream is substantially immiscible with the first stream. The streams are introduced into the conduit reactor such that they are in contact and the extractant of the first stream interacts with the second stream to extract the metal element, a metal compound, a metalloid element, and/or a metalloid compound from the second stream into the first stream. The method further includes receiving the first and second streams in collection vessel/s and withdrawing separately the first and second streams from collection vessel/s.

  • Patent number: 9433922
    Abstract: Media and devices, such as anion exchangers including such media, wherein the media is a membrane having a surface coated with a polymer such as a polyallylamine. The resulting membrane offers stronger binding of protein impurities and superior removal of host cell proteins from biological samples than conventional ligands based on quaternary ammonium salts, including trimethylammonium ligands. Also described is a chromatography scheme and method for purifying monoclonal antibodies, wherein the anion exchange sorber is placed downstream of an affinity column (such as Protein A or Protein G affinity column) and optionally one or more polishing devices such as cationic exchange columns. Little or no dilution of the cation exchanger pool (or affinity column exchange pool where no cation exchanger is used) is necessary to lower the conductivity of the sample. The sorber functions well to strongly bind host cell proteins and other impurities in biological samples even at high conductivities and pH.

  • Patent number: 9428412
    Abstract: A process for treatment of water. Hardness and non-hydroxide alkalinity are removed from feedwaters in amounts to substantially avoid scaling when concentrated. Sparingly ionizable components in the feedwater are urged toward increased ionization by increasing the pH of the feedwater, and, in an embodiment, up to about pH 10.5, or higher. In this manner, species such as silica become highly ionized, and (a) their rejection by membranes used in the process is significantly increased, and (b) their solubility in the reject stream from the membrane process is significantly increased. Sparingly ionized species such as boron, silica, and TOC are highly rejected, and thus, their passage through the membrane is reduced by a factor of ten or more. Recovery ratios of ninety percent (90%) or higher are achievable with many feedwaters, while simultaneously achieving a substantial reduction in cleaning frequency of membranes used in the process.

  • Patent number: 9421282
    Abstract: The present invention provides a technique for adsorbing I-125 on a support for treating cancer and a method of preparing an I-125 seed using the same. Since a method of preparing iodine according to the present invention uses an intermediate having phosphate-based, oxalate-based, or arsenate-based anions introduced thereinto, the intermediate has a substitution effect of iodine 3 to 5 times higher than that of a typically used intermediate having chlorine anions introduced thereinto. According to the substitution effect, control of a radiation dose may be possible during the manufacturing of an iodine seed and an iodine seed may be prepared within a shorter period of time. Also, since an amount of residual radioactive iodine may be decreased as a result of a large amount of adsorption, an amount of radioactive iodine (I-125) waste may be decreased, and the effect thereof may be also high environmentally.

  • Patent number: 9408370
    Abstract: Systems and methods remove and manage heavy metals. In one implementation, an exemplary method can be applied to food processing and food consumption to remove heavy metals such as mercury, lead, uranium and cadmium before absorption by a living organism. The exemplary method exposes the food to a heavy-metal binding ligand, such as a concentrated protein or phytic acid, to form a heavy-metal chelate, and then allows the chelate to separate from the food. In another implementation, an exemplary probe possesses innovative molecular layers on its surface to detect and quantify heavy metals by attracting and binding traces of the heavy metals on a ligand layer.
