“…When Fe 3þ appeared in the system, the degradation rate of glyphosate by Fe 3þ reached~50% after 360 min under sunlight irradiation. Because Fe 3þ light absorption occurs at wavelengths >200 nm, the simulated sunlight conditions caused the absorption of photons at 300 nm, which produced active species (Chen et al, 2007(Chen et al, , 2011. Reactions between glyphosate and the active species can occur and promote the transformation form.…”

“…The Fe 3þ photochemical activity was clearly influenced by some of the environmental factors (Chen et al, 2007). Therefore, the initial concentrations of glyphosate, Fe 3þ , and humic acid and the initial pH were chosen to determine the effects of the environmental parameters of the water on the phosphate release rate by Fe 3þ .…”

“…[118][119][120][121] Studies have also shown that phosphonates, particularly glyphosate, can be broken down by Fe-catalysed photolysis, at least in the laboratory. [122] Ecological significance Again, little is known on the ecological significance of phosphonates. Based on the loss of phosphonates from particulate matter with depth it has been suggested [110] that phosphonates may be an important and unrecognised source of P to aquatic environments, at least for some organisms.…”

Environmental context. Organic phosphorus can be one of the major fractions of phosphorus in many aquatic ecosystems. This paper discusses the distribution, cycling and ecological significance of five major classes of organic P in the aquatic environment and discusses several principles to guide organic P research into the future.Abstract. Organic phosphorus can be one of the major fractions of phosphorus in many aquatic ecosystems. Unfortunately, in many studies the 'organic' P fraction is operationally defined. However, there are an increasing number of studies where the organic P species have been structurally characterised -in part because of the adoption of 31 P NMR spectroscopic techniques. There are five classes of organic P species that have been specifically identified in the aquatic environment -nucleic acids, other nucleotides, inositol phosphates, phospholipids and phosphonates. This paper explores the identification, quantification, biogeochemical cycling and ecological significance of these organic P compounds. Based on this analysis, the paper then identifies a number of principles which could guide the research of organic P into the future. There is an ongoing need to develop methods for quickly and accurately identifying and quantifying organic P species in the environment. The types of ecosystems in which organic P dynamics are studied needs to be expanded; flowing waters, floodplains and small wetlands are currently all under-represented in the literature. While enzymatic hydrolysis is an important transformation pathway for the breakdown of organic P, more effort needs to be directed towards studying other potential transformation pathways. Similarly effort should be directed to estimating the rates of transformations, not simply reporting on the concentrations. And finally, further work is needed in elucidating other roles of organic P in the environment other than simply a source of P to aquatic organisms.

Due to extensive variety of nuclear applications, the cost efficient adsorbent is extremely needed for radioactive liquid waste solutions treatment. Bentonite which is consists essentially of clay minerals of the smectite group; have a wide range of industrial uses. In this study, a simple approach to adsorb uranium (VI) from aqueous solution by exchangeable cation by sodium bentonite clay is presented. The effects of contact time, pH of the solution, initial uranium (VI) concentration, adsorbent dosage, and solution temperature on the adsorption of uranium (VI) ions from radioactive liquid solution were investigated. Adsorption isotherms were expressed by Langmuir and Freundlich adsorption models. The theoretical capacity of sodium bentonite clay adsorbent is about 12 mg/g. The optimum adsorption conditions were recommended. About 89% of the loaded Uranium (VI) on modified clay adsorbent was eluted by CH 3 COONa as an efficient eluent. The preferred adsorption and elution conditions were applied on real waste sample and the obtained capacity was determined.
