TL;DR: In this paper, a gamma radiation-induced polymerization of acrylic acid (AAc) onto polyvinylbutyral (PVB) film has been carried out under nitrogen atmosphere.
Abstract: Gamma radiation-induced polymerization of acrylic acid (AAc) onto polyvinylbutyral (PVB) film has been carried out under nitrogen atmosphere. The grafted film of PVB-g-PAAc was allowed to react with solutions of two ionic dyes (ion exchange), namely brilliant green (BG) or methylene green (MEG). The results show that these new dosimeter films of PVBBG and PVBMEG may be useful for high-dose radiation dosimetry applications. We concluded that, the useful absorbed dose range of the dyed films extends up to about 400 and 300 kGy respectively.

TL;DR: In this article, a new nanostructure of Eu-MOF was synthesized through facial, fast, and cost-effective ultrasound assisted reverse micelle (UARM) method.
Abstract: In recent years, one of the growing environmental concerns has been contamination of water sources by dyes. For solving this problem, different nanostructures with various potential have been suggested. Among these nanostructures, Metal Organic Frameworks (MOFs), novel porous crystalline nanostructures with unique physiochemical properties, have drawn great attention for removal of dyes from different solutions. In this work, a new nanostructure of Eu-MOF was synthesized through facial, fast, and cost-effective ultrasound assisted reverse micelle (UARM) method. This nanostructure was developed for sonocatalytic and sonophotocatalytic degradation of brilliant green dye (BG) from aqueous solution. Further, 2 k−1 factorial design was used for investigating the effect of various experimental parameters including catalyst dosage, contact time, initial dye concentration, ultrasonic power, and pH on the sonocatalyst and sonophotocatalyst behaviors of Eu-MOF. The results of analysis of variance confirmed that these parameters have a significant effect on the degradation efficiency of brilliant green by Eu-MOF. For achieving the best optimization of the BG degradation, the response surface methodology was applied. According to this methodology, the Eu-MOF has a significant potential for BG degradation as high as 99%.

TL;DR: In this paper, the adsorption study of a synthetic dye namely Brilliant Green (BG) used frequently in the textile industries, using a natural and a low-cost adsorbent, which is locally available.
Abstract: This paper deals with the adsorption study of a synthetic dye namely Brilliant Green (BG) used frequently in the textile industries, using a natural and a low-cost adsorbent, which is locally available. The adsorbent used in this work is the Beech sawdust, collected from an industrial unit of wood in Fez city (Morocco) and which is characterized before by various techniques. The study of the adsorption potential of this dye on Beech sawdust and the monitoring of the influence of several parameters on this adsorption were evaluated. The analysis of the results obtained during this study showed that the adsorption rate of Brilliant Green dye reached a percentage of about 82% with a maximum concentration of 80 ppm. The optimum mass of Beech sawdust used is 1.25 g in a volume of 100 ml. The mixture was agitated for90 min as a contact time at ambient temperature. The adsorption isotherms modeling obtained is consistent with the Langmuir model and the kinetic data follows the pseudo-second order model. This study revealed that the Beech sawdust is very effective in removing Brilliant Green as a cationic dye, which making these sawdust an effective alternative for the removal of cationic dyes from polluted water.
