Reactions between Manganese Dioxide and Aqueous Sulfide

Publikováno v: Environmental Letters. 7:163-173

Rates of reaction of aqueous sulfide with excess suspended manganese dioxide showed a first-order dependence with respect to sulfide concentration under oxygen-free and oxygen-present conditions. In both cases, calculated rate constants showed a simi

Fate of cyanide and related compounds in aerobic microbial systems—I. Chemical reaction with substrate and physical removal

Autor: M. A. Kessick, William G. Characklis, S. F. Raef, C. H. Ward

Publikováno v: Water Research. 11:477-483

The chemical reaction of cyanide with substrate was investigated in sealed glass ampoules using glucose as substrate and inorganic buffers. The reaction was found to be pseudo-first order and pH dependent, with an optimum pH near 11.0. The cyanide-gl

Electrophoretic mobilities of virus adsorbing filter materials

Autor: M. A. Kessick, R.A Wagner

Publikováno v: Water Research. 12:263-268

Surface charge characteristics of virus adsorbing filters were studied by electrophoretic measurements of particulate suspensions under conditions commonly encountered in the adsorption technique for virus concentration. A mechanism for virus interac

Recovery of residual bitumen from oil sand sludges

Autor: M. A. Kessick, C. E. St. Denis

Publikováno v: The Canadian Journal of Chemical Engineering. 60:675-679

Factorial experiments were conducted to examine the effects of dilution, caustic addition and lime addition on the recovery of residual bitumen by flotation from oil sands tailings sludges. Dilution was found to be the most significant variable, and

Pipeline flow behaviour of heavy crude oil emulsions

Autor: Barbara E. Wyslouzil, M. A. Kessick, Jacob H. Masliyah

Publikováno v: The Canadian Journal of Chemical Engineering. 65:353-360

Pipeline transportation of heavy oils as oil-in-water emulsions has been proposed as an alternative to blending the crude oil with natural gas condensate or other diluent. An 18 m long, 0.02 m I.D. closed loop was constructed to investigate the behav

Fate of cyanide and related compounds in aerobic microbial systems—II. Microbial degradation

Autor: William G. Characklis, M. A. Kessick, S. F. Raef, C. H. Ward

Publikováno v: Water Research. 11:485-492

Cyanide metabolism was studied using starved, acclimated heterogeneous cultures in an aerated microfermenter containing glucose as substrate. Tests using K 14 CN indicated that up to 50% of the cyanide was metabolized as evidenced by 14 CO 2 producti
