  • Removal of biological pathogens using surfactant-modified zeolite
    Patent number: 7311839
    Abstract: Systems and methods are described for removing biological pathogens using surfactant-modified zeolite (SMZ). A method for removing biological pathogens from a fluid or a fluid-based gel includes filtering the fluid or fluid-based gel using SMZs. A method for removing air-borne biological pathogens includes drawing air through a fluid layer or a fluid-based gel layer and filtering the fluid or the fluid-based gel layer using SMZs.

  • Production and article of iron/surfactant-modified zeolite pellets to retain and destroy water pollutants
    Patent number: 6261986
    Abstract: A method of producing a pollutant adsorption and degradation article, and such article, are provided. At least one adsorbent is mixed with at least one pollutant transforming agent to form a mixture. This mixture is compacted to form a porous, highly permeable article. If necessary, the article can be modified with surfactant either after the compacting step or by adding the surfactant to the mixture prior to the compacting step. In addition, if necessary, a binding agent can be added to the mixture prior to the compacting step.

  • Bicharge photoconductive zinc oxides containing iodine
    Patent number: 3948658
    Abstract: Bicharge photoconductive zinc oxides useful in the production of photoprint papers providing good quality photoprints in both positive charge and reversal modes are prepared by heating photoconductive zinc oxide in air to a temperature of from about 100.degree.C. to about 500.degree.C. in the presence of iodine or an inorganic or organic iodide.
