On the Mechanism of the Ionizing Radiation-Induced Degradation and Recycling of Cellulose.

The use of ionizing radiation offers a boundless range of applications for polymer scientists, from inducing crosslinking and/or degradation to grafting a wide variety of monomers onto polymeric chains. This review in particular aims to introduce the field of ionizing radiation as it relates to the degradation and recycling of cellulose and its derivatives. The review discusses the main mechanisms of the radiolytic sessions of the cellulose molecules in the presence and absence of water.

Gamma irradiation-induced degradation and mineralization of methocarbamol in aqueous solution.

Gamma irradiation degradation of the extensively used muscle relaxant in the world methocarbamol (MET) was studied. MET aqueous solutions were irradiated by gamma rays emitted by a Cobalt 60 source at doses of 1-4 kGy. Our findings demonstrated that gamma irradiation degraded more than 98.

Kinetic and mechanism investigation on the gamma irradiation induced degradation of quizalofop-p-ethyl.

An efficient gamma radiolytic decomposition of one of the extensively used herbicides in the world quizalofo-p-ethyl (QPE) was explored under different experimental conditions. Aqueous solutions of QPE were irradiated by gamma rays emitted by a Cobalt 60 source. QPE aqueous solutions were irradiated at doses of 0.

Gamma radiation induced degradation of the phenoxy acid herbicide diclofop-methyl in aqueous solutions.

Gamma radiation of diclofop methyl (DM) an herbicide deriving from aryloxy-propionic acid was investigated. DM aqueous solutions was irradiated at different doses from 1 kGy to 8 kGy. The effects of radiation doses on UV-visible spectroscopy, pH, total inorganic carbon (TOC) and kinetic study have been studied.
