An anion exchange resin from soybean hulls
Agricultural by-products are generally poor adsorbents of anions in solution. Therefore, modification of the by-product could enhance its anion exchange capabilities. The objective of this study was to increase the anion exchange properties of the agricultural by-product, soybean hulls, by chemical modification. Soybean hulls were quaternized with the quaternizing agent, N-(3-chloro-2hydroxypro...
متن کاملContamination of Commercial L-leucine Preparations with Methionine and Cystine.
methods to remove methionine from L-leucine (Fox, Science 84:163, 1936; Bergmann and Stein, J. Biol. Chem. 129:609, 1939), I was surprised to find that certain current preparations of commercial L-leucine, supposedly of high quality, are heavily contaminated with methionine and also with cystine. In an examination of the requirements of a series of Bacillus subtilis mutants, the four types show...
متن کاملProcedure to Reduce Sulphite in Wine with Anion-exchange Resin
HORÁK, M., HÍC, P., TOMÁNKOVÁ, E., BALÍK, J.: Procedure to reduce sulphite in wine with anion-exchange resin. Acta univ. agric. et silvic. Mendel. Brun., 2012, LX, No. 8, pp. 79–86 The aim of this experiment was to eliminate SO2 ions present in wine using the anion-exchanger resins. To compare the eff ectiveness, 2 following strongly basic anion-exchange resin were used. When activated, the sod...
متن کاملPrediction of oligodeoxyribonucleotides eluting salt conditions on anion exchange column
Chromatography is commonly used as a purification method for synthetic oligodeoxyribonucleotides (1). Anion exchange chromatography on Mono Q column (Pharmacia), under denaturing conditions and using non-organic buffers, gives adequate purity for sequences up to 50 bases long (2). The eluting NaCl concentration primarily depends on the oligonucleotide length. However, base composition and seque...
متن کاملCompatibility between self-etching adhesive and self-curing resin by addition of anion exchange resin.
OBJECTIVE The aim was to investigate whether anion exchange resin powder in the OH(-) form, added to the amine component of self-cured resin can deprotonize acid groups of a self-etching adhesive and thus eliminate incompatibility caused by amine neutralization. METHODS Shear bond strength (SBS) of a self-cured CorePaste (COP), bonded either with all-in-one adhesive iBond (IBO) or with IBO co...
