desinfection of water by chemical oxidants

Interaction of Chemical Oxidants with Aquifer Materials

Inactivation by Airborne Oxidants'

Sunmmiary. Particuilate cell wall polysaccharide synthetase from oat coleoptiles could use either guanosine diphosphate glucose or turidine diphosphate glucose; the latter was a much more effective glucose donor. The neutral polymer derived from uridine diphosphate glu-cose utilization yielded, after cellulase digestion, mostly cellobiose and to a lesser extent a suibstance tentatively identifi...

Chemical oxidants acidify solitary complex (SC) neurons in the rat.

Breathing high levels of oxygen (i.e. hyperoxia) causes hyperventilation and unstable breathing in normal and carotid-deafferented animals (1,2). Prolonged exposure to hyperoxia can disrupt central nervous system (CNS) function and result in a condition termed CNS O2 toxicity, the primary sign of which is convulsion (3,4). The mechanism by which hyperoxia stimulates ventilation and disrupts CNS...

Occurrence of by-products of strong oxidants reacting with drinking water contaminants--scope of the problem.

This paper describes results of a detailed literature review of the organic and inorganic by-products that have been identified as being formed in aqueous solution with four of the strong oxidizing/disinfecting agents commonly employed in drinking water treatment. These agents are: chlorine, chlorine dioxide, chloramine, and ozone. Significant findings include the production of similar nonchlor...

Production of photo-oxidants by dissolved organic matter during UV water treatment.

Dissolved organic matter (DOM) irradiated by sunlight generates photo-oxidants that can accelerate organic contaminant degradation in surface waters. However, the significance of this process to contaminant removal during engineered UV water treatment has not been demonstrated, partly due to a lack of suitable methods in the deep UV range. This work expands methods previously established to det...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
