BACKGROUND Enzymatic elimination of synthetic dyes, one of the most environmentally hazardous chemicals, has gained a great interest during the two last decades. The present study was performed to evaluate the decolorization and detoxification potential of the purified laccase of Paraconiothyrium variabile in both non-assisted and hydroxybenzotriazole-aided form against six azo dyes. RESULTS ...
در این پروژه تاثیر حرارت و نوع حرارت (حرارت خشک، بخار اشباع و آب داغ) بر روی رفتار رنگرزی پارچه نایلونی(نایلون 6) با رنگهای اسیدی و مستقیم مورد بررسی قرار گرفت. پارچه ها در حرارت خشک در دما های 160، 170، 185 و 200 درجه ، برای حرارت در بخار اشباع دما های 100 و 120 و برای آب داغ 130، 140 و 150 انتخاب شد. برای رنگرزی از هر گروه دو رنگ در کلاس های متفاوت استفاده شد : رنگ c.i. acid orange 7 از گروه ...
Four Korean kernel fruit (apple, pear, persimmon, and mandarin orange) juices were obtained by household processing techniques (i.e., blending, juicing). Whole and flesh fractions of each fruit were extracted by a blender or a juicer and then examined for phytochemical content (i.e., organic acids, polyphenol compounds). The antioxidant capacity of each juice was determined by ferric reducing a...
Terpenoid volatiles are isoprene compounds that are emitted by plants to communicate with the environment. In addition to their function in repelling herbivores and attracting carnivorous predators in green tissues, the presumed primary function of terpenoid volatiles released from mature fruits is the attraction of seed-dispersing animals. Mature oranges (Citrus sinensis) primarily accumulate ...
Application of modified red mud for adsorption of Acid Orang 7 (AO7) dye from aqueous solution: Isotherms, Kinetics studies Abstract: Backgroud: Existence of color is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study is evaluation of adsorption rate of acid orange (AO7) from aqueous solution by act...
It is well known that eating fruits and vegetables lowers the risk of chronic diseases such as heart disease and cancer. The question of what is/are the active ingredient(s) is still unresolved. The initial hypothesis was that the antioxidant vitamins were responsible. However, recently the polyphenols have been investigated since they have been found to have beneficial properties such as being...
Poly(ionic liquid)s nanofiber (PIL NF) membrane was derived from polyacrylonitrile by converting its cyano groups to imidazoline moieties via cyclization with ethylenediamine, followed quaternization 1-bromobutane. The novel PIL NF is further decorated photocatalyst phosphotungstic acid PW12 anion exchanging give PW-PIL. degradation rate of the supported towards methyl orange irradiated under v...
Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was observed with oxone in solutions with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2+] with a rate constant of 20 M−1 s−1. Fitting of the Orange II photobleaching experimental points in the presence of the Co2+/oxone re...
