Linear and branched-chain (C4–C18) alkylbenzenesulfonates are separated by this method according to the length and structure of the alkyl chain, using as the mobile phase 0.1 mol L−1 tetrabutylammonium hydrogensulfate (pH 5)–water–acetonitrile (gradient elution). At pH 5, the sulfonates ...

Thermodynamic analysis of possible chlorination reactions in roasting process was calculated and the Predominance Area Diagram of Ni–Co–Cl–H–O was shown to indicate the effect of partial pressure of HCl and H2O on the stability of NiCl2 and CoCl2. The mixture of NaCl and MgCl2·6H2O was ...
Metal recycling plays a crucial role in mitigating the shortage of critical metals and reducing reliance on primary mining. Current liquid hydrometallurgy involves substantial water and chemical consumption with troublesome secondary waste streams, while
Structure Diagram The system configuration : Chlorine dioxide generator host, reaction kettle, hydrochloric acid storage tank, sodium chlorate storage tank, chemical material, chemical material pump, hydrochloric acid metering pump, sodium chlorate metering pump, water injector, indoor...

Escherichia coli is an important pathogenic indicator in drinking water. Viable but non-culturable (VBNC) E. coli induced by low level chlorination was found to have higher antibiotic tolerance. The emerging of VBNC bacteria in drinking water systems is
Fig. 1. Electrochlorinator diagram. The feed consists of a sodium chloride solution of approximately 30 g/l, sea water or wastewater (Black & Veatch Corporation, 2009). The water is typically softened and strained if necessary. At the cathode, water is electrolyzed into hydrogen gas and hydro...
1.A chlorination system for feeding a chlorine solution into a supply of water, the system comprising:a source of chlorine solution;a case mountable adjacent said source of chlorine solution, said case defining a back interior surface;a generally planar zinc coated back plate attached to said bac...
and an acid supply system for adding hydrochloric acid to the pool as required. Generation of chlorine and addition of acid are controlled automatically in response to sensed oxidation-reduction potential (ORP) and pH of the swimming pool water. The sensors for this purpose may be placed in a...
