Sep 08, 2006· Corynebacterium glutamicum grew on resorcinol as a sole source of carbon and energy. By genome-wide data mining, two gene clusters, designated NCgl1110-NCgl1113 and NCgl2950-NCgl2953, were proposed to encode putative proteins involved in resorcinol catabolism.
added, to this solution. The flotation cell was then inverted upside down for few minutes by hand. After 10 min, to ascertain complete flotation, the concentration of the metal ion in the scum was determined spectrophotometrically. To confirm the results obtained spectrophotometrically, the concentration of
An experimental investigation is presented on flotation of Cs+, Sr2+ and Ba2+ cation metals from dilute aqueous solutions using lariat ethers with a novel protonionizable group in the presence of ing agent.
The Selective Flotation of Cesium Ion with Resorcinol-Type Calix(4)arenes with Alkyl Side Chains. Yoshifumi Koide, Tetsushi Oka, Akemi Imamura, Hideto Shosenji, Kimiho Yamada Bulletin of the Chemical Society of Japan 1993 66 (8), 2137-2142
The extraction of uranium from seawater was studied by the Japan Tobacco and Salt ... (solvent extraction, ion exchange, flotation, biomass collection, adsorption), and development of adsorbents ... Ordinary organic ion exchange resins, such as the resorcinol arsenic acid formaldehyde
removal of the ion flotation process of mentioned cations are presented in Fig. 1. It was found that, the longer the chain the greater the maximal percent removal of both cations from diluted aqueous solutions, however a percent removal for the barium cations is higher than for the cesium.
Autorzy artykułu przedstawili badania selektywnego wydzielania wybranych kationów metali z rozcieńczonych roztworów wodnych z użyciem nowej grupy związków makrocyklicznych, tj. jonizowanych eterów lariatowych w obecności spieniacza niejonowego.
collectors for ion flotation process. In a limited number of papers, macrocyclic compounds have been utilized in separation of metal ionic species using ion flota-tion process. Koide and Oka studied resorcinol-type calix[4]arenes with alkyl side chains as collectors in …

pilot-scale hydraulic testing of spherical resorcinol formaldehyde (RF) ion exchange resin in support of the River Protection Project in Richland, Washington. The purpose of this project is to design, construct, and commission a plant to treat and immobilize high-level
Kiteboarding Flotation Vests at Big Winds Big Winds Hood River is a locally-owned windsurfing, kiteboarding and standup paddle boarding shop located in Oregons Columbia Gorge, offering gear, lessons and rentals.
Ion flotation is a separation method known since the early 1960s, and can be effective for removal of ionic species from dilute aqueous solutions (c Me ≤ 1 × 10 −4) . The selectivity of ordinary ionizable surfactants (collectors) towards cations and/or anions is limited.
Maciejewski, 2009). Koide et al. (1993) investigated resorcinol-type calix[4]arenes with alkyl side chains as collectors in competitive flotation of alkali metal cations and showed selective flotation of Cs+ +over Na and K+ cations from dilute aqueous solutions. On the other hand, Koide and co-workers (1996) separated UO 2 2+ cations
Flotation spectrophotometric determination of … Flotation of the complex was carried out with heptane, followed by dissolution in N,N-dimethylformamide (DMF) …
Resorcinol is a 1,3-isomer (or meta-isomer) of benzenediol with the formula C6H4(OH)2. It is used as an antiseptic and disinfectant in topical pharmaceutical products in the treatment of skin disorders and infections such as acne, seborrheic dermatitis, eczema, psoriasis, corns, calluses, and warts.

4-(2-pyridyl-Azo) resorcinol mono sodium mono hydrate (NaPAR), a heterocyclic azo dye, was investigated for the flotation of copper (II). The metal ion forms a faint red complex with NaPAR in ...
It is based on flotation of a complex of Pb 2+ ions and Alizarin yellow between aqueous and n-hexane interface at pH = 6. The proposed procedure is also applied for determination of lead in both tap water and prepared sea water samples.
In addition, selective flotation of cesium ion has been reported using resorcinol-type calix[4]arenes with alkyl side chains . Thus, calixarenes have been paid attention as new functional materials. Thus, calixarenes have been paid attention as new functional materials.
