There is no access to basic sanitation for half the world's population, leading Socioeconomic issues, such as scarcity of drinking water and spread diseases. In this way, it vital importance develop management technologies relevant target population. addition, in separation form treatment, compound often used a coagulant treatment aluminum sulfate, which provides good results raw turbidity colo...

in this work, benzyl alcohol was obtained in 96% excellent yield by hydrolysis of benzyl chloride catalyzedby the recyclable temperature-dependant phase-separation system that comprised the ionic liquid peg1000-dail[bf4], toluene and ferric sulfate under homogeneous catalysis in aqueous media. this novel methodnot only enhanced the yield, but also made the operating units easy workup. the catal...

In anaerobic sediments, microbial degradation of petroleum hydrocarbons is limited by the rapid depletion electron acceptors (e.g., ferric oxide, sulfate) and accumulation toxic metabolites sulfide, following sulfate reduction). Deep-sea sediments are increasingly impacted oil contamination, elevated hydrostatic pressure (HP) they subjected to represents an additional limitation for metabolism....

Ferrous carbonate was precipitated from the reaction of ferrous sulfate and sodium carbonate in an aqueous medium. The precipitate was calcined at different~eating rates (2, 5 and 10 °C/min, respectively) up to 500°C and the iron oxides produced were found to be magnetic. X-ray diffraction studies indicated the presence of gamma ferric oxide as a major phase in all the cases. It was found that ...

A new anaerobic, thermophilic, facultatively carboxydotrophic bacterium, strain Nor1(T), was isolated from a hot spring at Norris Basin, Yellowstone National Park. Cells of strain Nor1(T) were curved motile rods with a length of 2.6-3 microm, a width of about 0.5 microm and lateral flagellation. The cell wall structure was of the Gram-negative type. Strain Nor1(T) was thermophilic (temperature ...

Introduction: Mapping the type and distribution of hydrated mineralogy is one way to track the aqueous history of Mars. Sulfates are a potentially good tracer of past climate because they form by aqueous processes , so their presence, volume, and process of formation can characterize how much water was available. The sulfates in Valles Marineris (monohydrated Mg or Fe sulfate and polyhydrated s...
