Toxic organics

Disinfeetion. Chlorine, as gaseous chlorine or as the h5rpochlorite ion, is widely used as a disinfectant. However, its use in some cases can lead to the formation of toxic organic chlorides, and the discharge of excess chlorine can be harmful. Ozone as an alternative disinfectant leads to products that have a lower toxic potential. Treatment is enhanced by ultraviolet light. Indeed, disinfection can be achieved by ultravifflet light on its own. [Pg.319]

In order to handle accidental spills or overflows, a spill basin maybe provided, into which the flow is diverted if the concentration of a particular constituent exceeds a predetermined value. If equalization precedes biological treatment, in addition to the organic loading, high fluctuations in temperature, salinity, and toxic organics must also be considered. After the spill is contained, the wastewater flow is diverted back to the equalization basin. The contents of the spill basin are then pumped at a constant controlled rate to the equalization basin. [Pg.180]

The nitrifying organisms are relatively sensitive to many toxic organics, so that the treatment of industrial wastewaters requires special attention to the presence of toxics. [Pg.189]

Toxic Organic Materials. The term toxic organics iacludes synthetic organic compounds such as pesticides, herbicides, PCBs, and chlotinated hydrocarbons, usually produced by the manufacturers and formulators of these products. [Pg.226]

The immobilization of reagents onto sorbents often results in increase of their sensitivity and, in some cases, selectivity, allows to simplify the analysis and to avoid necessity of use of toxic organic solvents. At the same time silicas are characterized by absence of swelling, thenual and chemical stability, rapid achievement of heterogeneous equilibrium. [Pg.60]

MODERN STATE AND PROGRESS TRENDS OF CHROMATOGRAPHIC METHODS OF ANALYSIS OF TOXIC ORGANIC SUBSTANCES IN UKRAINE Chmil V.D.. Grinko A.P. [Pg.65]

Presently efforts of Ukrainian scientists in field of analysis of toxic organic substances directed on harmonization of the developed methods of analysis with the requirements of international standards and on wide introduction in practice of the quality control system in chromatographic researches. [Pg.65]

Intensive application of pesticides and polymers in agriculture and industry cause the increase of number of toxic organic substances, which circulate in an environment, and constantly complicates their disclosure, identification and quantitative detection. [Pg.189]

The aqueous micellai solutions of some surfactants exhibit the cloud point, or turbidity, phenomenon when the solution is heated or cooled above or below a certain temperature. Then the phase sepai ation into two isotropic liquid phases occurs a concentrated phase containing most of the surfactant and an aqueous phase containing a surfactant concentration close to the critical micellar concentration. The anionic surfactant solutions show this phenomenon in acid media without any temperature modifications. The aim of the present work is to explore the analytical possibilities of acid-induced cloud point extraction in the extraction and preconcentration of polycyclic ai omatic hydrocai bons (PAHs) from water solutions. The combination of extraction, preconcentration and luminescence detection of PAHs in one step under their trace determination in objects mentioned allows to exclude the use of lai ge volumes of expensive, high-purity and toxic organic solvents and replace the known time and solvent consuming procedures by more simple and convenient methods. [Pg.422]

HAZARDOUS WASTE An Unofficial class of industrial wastes which have to be disposed of with particular care. In the UK the closest definition is for special wastes . Certain toxic organic wastes, such as PCBs, have to be burned in high-temperature incinerators. [Pg.14]

NOTE - Petrochemical plants also generate significant amounts of solid wastes and sludges, some of which may be considered hazardous because of the presence of toxic organics and heavy metals. Spent caustic and other hazardous wastes may be generated in significant quantities examples are distillation residues associated with units handling acetaldehyde, acetonitrile, benzyl chloride, carbon tetrachloride, cumene, phthallic anhydride, nitrobenzene, methyl ethyl pyridine, toluene diisocyanate, trichloroethane, trichloroethylene, perchloro-ethylene, aniline, chlorobenzenes, dimethyl hydrazine, ethylene dibromide, toluenediamine, epichlorohydrin, ethyl chloride, ethylene dichloride, and vinyl chloride. [Pg.57]

Raw material input to petroleum refineries is primarily crude oil however, petroleum refineries use and generate an enormous number of chemicals, many of which leave the facilities as discharges of air emissions, wastewater, or solid waste. Pollutants generated typically include VOCs, carbon monoxide (CO), sulfur oxides (SOJ, nitrogen oxides (NOJ, particulates, ammonia (NH3), hydrogen sulfide (HjS) metals, spent acids, and numerous toxic organic compounds. [Pg.101]

Polychlorinated biphenyls (PCBs) Highly toxic organic compounds used in the electrical industry, use of w hich is now restricted. [Pg.1467]

On-line LC-GC has frequently been used as a clean-up technique for the analysis of trace levels of contaminants (pesticides, plasticizers, dyestuffs and toxic organic chemicals) in water and food products. Several different approaches have been proposed for the analysis of contaminants by on-line LC-GC. Since pesticide residues occur at low concentration in water, soil or food, extraction and concentration is needed before GC analysis is carried out. [Pg.238]

The NEMCA effect in aqueous electrochemistry may be of considerable technological value, for example in the electrochemical treatment of toxic organics or the production of useful industrial chemicals. [Pg.480]
