Malachite green (MG)
-
Complete photodegradation of MG was successfully achieved with the aid of the nanocomposites. The optimum photocatalytic degradation conditions, irradiation time, irradiation power, and amount of catalyst were studied. Photocatalytic activity of the synthesized nanocomposites in terms of degradation of MG was compared with that of undoped TiO2 (synthesized by our team) and chitosan under normal conditions. It was concluded that the synthesized nanocomposites had better photocatalytic activity. The best result (100% degradation) was obtained with amount of nTC of 0.

In this study, an effective adsorbent was synthesized to remove malachite green (MG), which is one of the toxic dyes. Firstly, single walled carbon nanotube with carboxylated acid (SWCNT-COOH) was functionalized with diethylenetriamine and a new nanocomposite was obtained using nano zinc oxide (ZnO) powder. The effects of pH (3–7), the amount of adsorbent (5–15 mg) and the initial concentration (10–50 mg L–1) of the solution on the adsorption uptake were investigated. The optimal parameters that maximize the adsorption uptake according to the specified working range are found to be 4.

Textile azo dyes are one of the pollutants in waste water that adversely affect human and environmental health. Removal of these chemicals from wastewater is important for eco-system and human health. In this study, Bi2 O3 nanoflakes and ZnO were synthesized by the co-precipitation method. Adsorption and photocatalytic degradation reactions were carried out to remove dyes (Victoria blue (VB) and Malachite green (MG)) from wastewater with the photocatalysts.

The removal of malachite green (MG) from aqueous solution using teak leaf litter powder (TLLP) was investigated. The process was influenced by initial concentration, pH and temperature of dye solution as well as TLLP dosage.

The purpose of this study was to investigate the feasibility of simultaneous optimization and removal of dyes, Malachite green (MG), Rhodamine B (RhB) and Cresol Red (CR) from aqueous solutions by using Sistan sand as an extremely low cost adsorbent. Factors affecting adsorption of the analytes on the sorbent were investigated experi‑ mentally and by using Taguchi and Plackett–Burman experimental design methods.

The structural and textural characterization of the as-prepared SERS substrates were characterised by scanning electron microscope (SEM), X-ray diffraction (XRD), and Raman spectroscopy. The SERS activity was studied by Raman scattering spetra of Malachite Green (MG) molecules in water at room temperature. The SERS results showed an enhancement (20 times) by coupling of MG molecules with a localized surface plasmon resonance of Ag NPs. The limit of detection of MG molecules was determined to be 10−7M.

Đề tài ”Nghiên cứu ảnh hưởng của Malachite Green lên sự biến đổi một số chỉ tiêu sinh hóa và tồn lưu trong cá tra (Pangasius hypophthalmus) giai đoạn giống” được thực hiện từ tháng 03/2006 đến 06/2006 nhằm mục đích xác định thời gian tồn lưu của Malachite Green và một số biến đổi sinh hóa trên cá tra. Thí nghiệm gồm hai nồng độ MG gây nhiễm: 0,1mg/l trong 12 giờ và 1mg/l trong 60 phút. Kết quả cho thấy hoạt tính của các men trong não, gan của cá Tra đều bị biến đổi và khả năng...
