Optimisation of radiolysis of Reactive Red 120 dye in aqueous solution using ionising 60Co gamma radiation by response surface methodology

by IWA Publishing  (Apr. 11, 2016)

In recent years, employing radiation technology is gaining great interest in degradation of industrial effluents. In this work the possibility of using gamma irradiation to degrade Reactive Red 120 (C.I.292775) was explored. The effects of pH, dose of gamma irradiation and concentration of dye were examined and their interaction were also ...

Is nuclear power our energy future — or a dinosaur in a death spiral?

by Ensia  (Feb. 29, 2016)

Identical data yield drastically different conclusions about the role nuclear will play in meeting climate goals. Nuclear power is dead. Long live nuclear power. Nuclear power is the only way forward. Nuclear power is a red herring. Nuclear power is too dangerous. Nuclear power is the safest power source around. Nuclear is nothing. Nuclear is ...

Photo‐enhanced toxicity of fluoranthene to Gulf of Mexico marine organisms at different larval ages and ultraviolet light intensities

by John Wiley & Sons, Ltd.  (Nov. 22, 2015)

Significant increases in toxicity have been observed as a result of PAH absorption of ultraviolet (UV) radiation in aquatic organisms. Early life stage aquatic organisms are predicted to be more susceptible to PAH photo‐enhanced toxicity as a result of their translucence and tendency to inhabit shallow littoral or surface waters. The objective ...

Can towns near Japan`s Fukushima nuclear plant recover?

by Associated Press  (Sep. 9, 2015)

A few signs of life are returning to this rural town made desolate by the Fukushima nuclear disaster four-and-a-half years ago: Carpenters bang on houses, an occasional delivery truck drives by and a noodle shop has opened to serve employees who have returned to Naraha's small town hall. But weeds cover the now rusty train tracks, there are no ...

Disinfection characteristics of the combined ultraviolet radiation and ozone process using Escherichia coli as a probe

by IWA Publishing  (Aug. 11, 2015)

In the present study, the characteristics of the combined ultraviolet (UV) and ozone disinfection process were investigated from kinetic and mechanistic viewpoints employing Escherichia coli (E. coli) as an indicator microorganism. Compared to individual unit processes, the combined UV/O3 tests produced excess hydroxyl radicals (HO•) and ...

How does climate stack up against other worst-case scenarios?

by Ensia  (Apr. 1, 2015)

Climate isn’t the only catastrophe threatening the planet, but it may be the one most in need of attention and resources. The following is excerpted from Climate Shock (2015) by Gernot Wagner and Martin L. Weitzman. Published here with permission from Princeton ...

Proven Protection In The World`s First Antimicrobial Classroom

by Waterlogic International Ltd  (Mar. 10, 2015)

The scientists at BioCote® recently ran a live test to measure and compare the number of bacteria in two classrooms in the same primary school. This was a world first as never before had an antimicrobial classroom been put under the microscope. The objective was to see how well BioCote antimicrobial protection performs in the classroom ...
