Filed:

Aug 9, 2000

Appl. No.:

09/634191

Inventors:

Nikolaos P. Nikolaidis - Storrs CT
Gregory M. Dobbs - Glastonbury CT
Jeffrey A. Lackovic - Gales Ferry CT

Assignee:

The University of Connecticut - Storrs CT

International Classification:

C02F 170

US Classification:

210719, 210747, 210757, 210911, 423601

Abstract:

A method for the remediation of arsenic is presented, comprising providing an aqueous solution of inorganic arsenic species, and passing the solution of inorganic arsenic species over a substrate comprising zero valent iron under anaerobic conditions, thereby reducing the arsenic species and forming arsenic-metal co-precipitates. Preferably, the metal is iron in the form of iron filings, and a source of sulfate ions is also present, resulting in the precipitation of arseno-pyrites.

US Classification:

4051285, 40512855, 40512875, 4051288, 405263, 588205, 588249, 210747, 210759, 210908

Abstract:

Volatile organic compounds are removed from contaminated soil by introducing one or both of a water soluble peroxygen compound, such as a persulfate, and a permanganate into the soil, either in situ or ex situ, in amounts and under conditions wherein both the soil oxidant demand is satisfied and volatile organic compounds in the soil are oxidized. In a preferred embodiment, when both are used, the peroxygen satisfies the soil oxidant demand and the permanganate oxidizes the volatile organic compounds. Sodium persulfate is the preferred persulfate and potassium permanganate is preferred permanganate. The persulfate and the permanganate may be added to the soil sequentially, or may be mixed together and added as an aqueous solution.

International Classification:

B01D 5322

US Classification:

165166, 96 7

Abstract:

Existing plate-type heat exchangers typically include plates that are constructed of metal or paper, which are only capable of transferring a limited amount of moisture, if any, from one side of the plate to the other side. The present invention is a plate-type heat exchanger wherein the plates are constructed of ionomer membranes, such as sulfonated or carboxylated polymer membranes, which are capable of transferring a significant amount of moisture from one side of the membrane to the other side. Incorporating such ionomer membranes into a plate-type heat exchanger provides the heat exchanger with the ability to transfer a large percentage of the available latent heat in one air stream to the other air streams. The ionomer membrane plates are, therefore, more efficient at transferring latent heat than plates constructed of metal or paper.
