Chemicals Subject to TSCA Section 12(B) Export Notification Requirements (January 16, 2020)
Chemicals Subject to TSCA Section 12(b) Export Notification Requirements (January 16, 2020) All of the chemical substances appearing on this list are subject to the Toxic Substances Control Act (TSCA) section 12(b) export notification requirements delineated at 40 CFR part 707, subpart D. The chemicals in the following tables are listed under three (3) sections: Substances to be reported by Notification Name; Substances to be reported by Mixture and Notification Name; and Category Tables. TSCA Regulatory Actions Triggering Section 12(b) Export Notification TSCA section 12(b) requires any person who exports or intends to export a chemical substance or mixture to notify the Environmental Protection Agency (EPA) of such exportation if any of the following actions have been taken under TSCA with respect to that chemical substance or mixture: (1) data are required under section 4 or 5(b), (2) an order has been issued under section 5, (3) a rule has been proposed or promulgated under section 5 or 6, or (4) an action is pending, or relief has been granted under section 5 or 7. Other Section 12(b) Export Notification Considerations The following additional provisions are included in the Agency's regulations implementing section 12(b) of TSCA (i.e. 40 CFR part 707, subpart D): (a) No notice of export will be required for articles, except PCB articles, unless the Agency so requires in the context of individual section 5, 6, or 7 actions. (b) Any person who exports or intends to export polychlorinated biphenyls (PCBs) or PCB articles, for any purpose other than disposal, shall notify EPA of such intent or exportation under section 12(b). -
Solvent Extraction of Iron(III) from Al Chloride Solution of Bauxite Hcl Leaching by Mixture of Aliphatic Alcohol and Ketone
metals Article Solvent Extraction of Iron(III) from Al Chloride Solution of Bauxite HCl Leaching by Mixture of Aliphatic Alcohol and Ketone Artem Sokolov 1 , Dmitry Valeev 2,* and Aleksandr Kasikov 1 1 Laboratory for the Development and Implementation the Chemical Technology Processes, Tananaev Institute of Chemistry—Subdivision of the Federal Research Centre, Kola Science Centre of the Russian Academy of Sciences, 184209 Apatity, Russia; [email protected] (A.S.); [email protected] (A.K.) 2 Laboratory of Sorption Methods, Vernadsky Institute of Geochemistry and Analytical Chemistry of the Russian Academy of Sciences, 119334 Moscow, Russia * Correspondence: [email protected]; Tel.: +7-905-781-6667 Abstract: Research into the solvent extraction of iron(III) from a chloride solution after bauxite HCl leaching by neutral oxygen-containing extractants and their mixtures were studied and the iron(III) extraction degree from chloride solutions using alcohols is presented. The effect of dilution of alcohol with a ketone by an extraction mixture in relation to its effectiveness was investigated. The iron(III) was efficiently extracted by the mixture of 1-octanol and 1-decanol (70%) with 2-undecanone (30%) from hydrochloric bauxite leach liquor at an O:A ratio = 2-4:1 at an iron(III) concentration of 7.4 g/L and 6 M HCl. For the removal of iron-containing organic phase from impurities (Al, Ca, Cr) that are co-extracted with iron(III), we used two step scrubbing at O:A = 5:1 by 7 M HCl as a scrub solution. The iron(III) stripping at the O:A ratio is shown. -

MacDiarmid Energy Research Institute, Chonnam National University, Gwangju 61186, Korea * Correspondence: [email protected] (M.C.); [email protected] (H.Y.); Tel.: +82-62-530-1771 (M.C.); +82-62-530-1778 (H.Y.) Received: 9 July 2018; Accepted: 13 August 2018; Published: 15 August 2018 Abstract: Hybrid organic–inorganic nanocomposites have attracted considerable attention because they have the advantages of both conjugated polymers (CPs) and nanocrystals (NCs). Recent developments in the interfacial engineering of CP–NC organic–inorganic nanocomposites enabled the formation of an intimate contact between NCs and CPs, facilitating electronic interactions between these two constituents. To design CP–NC nanocomposites, several approaches have been introduced, including ligand refluxing, direct grafting methods, direct growth of NCs in proximity to CPs, and template-guided strategies. In this review, the general reactions of ligand exchange processes, purification methods, and characterization techniques have been briefly introduced. This is followed by a highlight of recent advances in the synthesis of hybrid CP–NC nanocomposites and newly
