The present disclose is directed to a method for controlling iodine levels in wet scrubbers, and, in particular, recirculating wet scrubbers by removing the iodine from the scrubbing solution, such as by using ion exchange, absorption, adsorption, precipitation, filtration, solvent extraction, ion pair extraction, and an aqueous two-phase extraction.

A lithium adsorbent includes an aluminum-based adsorbing material, a binder, and a wetting and dispersing agent. The binder includes at least one of a vinylidene fluoride-chlorotrifluoroethylene (VDF-CTFE) copolymer and a fluoroolefin-vinyl ether copolymer. The wetting and dispersing agent includes one or more of polyethylene glycol, sodium polyacrylate, polyvinyl alcohol, and formaldehyde condensate.

The present invention relates to an adsorbent for treating an oil comprising a chlorophyll derivative. In particular, the present disclosure relates to an improved silica gel adsorbent for removing impurities, including chlorophyll derivatives and/or trace metals, from an oil, in particular triacylglycerol-based oils. The adsorbent comprises a silica gel treated with an alkali earth metal oxide, such as magnesium oxide, and has a pH of about 7 or greater and a water content of about 3 wt % or greater.

The present invention includes a composition and process for separating p-isomers of vinylbenzenes from a mixture of isomers comprising the steps of: providing a porous microwaved Mg(II) 2,4-pyridinedicarboxylic acid coordination polymer having a 1-D pore structure and showing reversible soft-crystal behavior by preferentially binding p-isomers of vinylbenzene; adding a mixture of vinylbenzenes isomers to the porous microwaved Mg (II) 2,4-pyridinedicarboxylic acid coordination polymer; adsorbing the p-isomers of vinylbenzene from the mixture of vinylbenzenes isomers; selectively adsorb the p-isomers of vinylbenzene in the 1-D pore structure; removing the mixture of vinylbenzenes isomers; and desorbing the p-isomers of vinylbenzene from the 1-D pore structure to purify the p-isomers of vinylbenzene.

In certain embodiments, the invention provides methods and devices for assaying single particles in a population of particles, wherein at least two parameters are measured for each particle. One or more parameters can be measured while the particles are in the separate reaction volumes. Alternatively or in addition, one or more parameters can be measured in a later analytic step, e.g., where reactions are carried out in the separate reaction volumes and the reaction products are recovered and analyzed. In particular embodiments, one or more parameter measurements are carried out “in parallel,” i.e., essentially simultaneously in the separate reaction volumes.
