Methyl-t-butylether (MTBE) is a synthetic ether that is mainly used as a fuel additive: it replaces lead in gasoline, increasing the anti-knock rating. Next to this it serves as an intermediate in the production of isobutylene and as a process solvent in the pharmaceutical industry. In clinical practice MTBE is used to dissolve gallstones. At room temperature MTBE is a colourless liquid with a ...

A novel Pd-based electro-Fenton (E-Fenton) process has recently been developed to transform organic contaminants in groundwater. However, it only produces H2O2 and requires addition of Fe(2+). In this study, an innovative approach is developed to effectively regulate the generation of Fe(2+) from an iron cathode in a three-electrode system in addition to H2O2 production. The Fe(2+) is then used...

I am pleased to be here today to discuss the increasing concern that our nations waters are becoming contaminated with methyl tertiary butyl ether (MTBE). About a third of the states, in certain areas, use gasoline that contains MTBE to help them limit air pollution because it burns cleaner. However, the substance could also pose risks to human health, especially as a contaminant in drinking wa...

Bank filtration of river or lake water represents an efficient and natural purification process used for the drinking water production in many countries and at an amount of about 15-16% in Germany. From experiences over decades particularly at the river Rhine and Elbe, it is known that the occurrence of persistent pollutants in river water can represent a problem for the quality of drinking wat...

Alcea nudiflora (Lindl.) Boiss. (Malvaceae) has a wide area of growth in Central Asia, the Altai territory and Western Siberia long been used folk traditional medicine. Availability resource long-term application practice makes promising source valuable biologically active natural compounds. The chemical composition A studied after effective microwave assisted extraction (MAE) performed using s...

Green buildings are increasingly being plumbed with crosslinked polyethylene (PEX) potable water pipe. Tap water quality was investigated at a six month old plumbing system and chemical and odor quality impacts of six PEX pipe brands were examined. Eleven PEX related contaminants were found in the plumbing system; one regulated (toluene) and several unregulated: Antioxidant degradation products...
