چکیده مقاله:
Malachite green is one of the aniline colored products and one of the drugs used in fish breeding, and it has been used in the fisheries and aquaculture industry since 1936 due to its specific characteristics. This substance is known as a mutagenic and carcinogenic compound. The use of this drug is prohibited for fish that is consumed by humans. Malachite green cancer was approved by the FDA[1,2]. Malachite green is a cationic color that is highly soluble in water.
Over the past decades, due to the dangerous problems that water pollution can cause to humans, extensive attention has been paid to the photocatalytic study of the release of organic pollutants in water[3].
In this study a zeolite imidazole framework (Cu(Him)2) was synthesized and checked out its photocatalytic application to eliminate Malachite green as an industrial color. The results showed that the increase in temperature and pH increased the adsorption of Malachite green. Increasing the amount of photocatalyst will reduce the absorption in the Malachite green.
Cu(Him)2 is susceptible to acidic conditions. The best decolonization conditions for the Malachite green are: in pH=8, with the lowest photocatalyst usage (0.0025 g) and 50 °C, will have a yield of about 99%.
