Las fuentes naturales con alto contenido de color y baja turbiedad, características una fuente superficial páramo, pueden limitar el proceso planta potabilizadora, ya que se genera velocidad sedimentación los flóculos formados en coagulación. El objetivo este documento es presentar resultado la investigación realizada al comparar producida por combinación cloruro férrico (FeCl3) e hidroxiclorur...

In this study, hybrid ultrafiltration which involves adsorption onto activated carbon and/or coagulation was tested for the removal of ibuprofen, caffeine and diclofenac from municipal wastewater treatment plant effluent (c0 = 2–3 µg/L). Ultrafiltration in combination with powdered dose 5 mg/L separately or coagulants (FeCl3, 4 mg Fe (III)/L and, natural coagulant isolated bean seeds, 33 µL/L)....

By combining the organometallic cyanides L n M-CN [L n M = Cp(dppe)Fe, Cp(dppe)Ru, Cp(PPh 3 ) 2 Ru] with FeCl 3 the dinuclear complexes L n M-CN-FeCl 3 were obtained. Structure determinations have revealed configurations close to linear arrays Fe-C-N-Fe and Ru-CN-Fe. From the n(CN) band positions in their IR spectra it can be concluded that FeCl 3 is a very strong electron acceptor. Accordingly...

enhanced coagulation (ec) is defined as the addition of excess coagulation to improve the removal of disinfection by-product (dbps) precursors through the use of conventional water treatment processes. in this research, most of coagulants of ferric chloride (fecl3), poly aluminum chloride(pacl) in removal of most parameters of total organic carbon (toc), dissolved organic carbon (doc), organic ...

FeCl3- and FeBr3-mediated tandem carboarylation/cyclization of propargylanilines with diethyl benzaldehyde acetals furnished the tetracyclic core of indeno[2,1-c]quinolines. 5-Tosyl-6,7-dihydro-5H-indeno[2,1-c]quinoline and 7H-indeno[2,1-c]quinoline derivatives were obtained in good to excellent yields, respectively, by tuning the FeX3 loadings and/or reaction temperatures.

In this paper we report some recent progress in 77GHz InP Gunn device process development. Specifically, utilizing an advanced dry etching tool to define InP Gunn diode mesas. Unlike FeCl3-based photochemical etches, the Inductively Coupled Plasma (ICP) offers excellent sidewall anisotropy and uniformity, which provides improved process consistency to facilitate mass manufacturablity of millime...
