Surface Modified Low Cost Adsorbent in Malachite Green Scavenging, Malachite Green/Rhodamine B and Malachite Green/Rhodamine B/Cu2+ Composite Treatment

Malachite Green Adsorption Behavior of Polyurethane/Chitosan Composite Foam

A composite foam of polyurethane/chitosan with chitosan content of 20 wt% was successfully prepared as an adsorbent for the removal of malachite green from aqueous solution, the structures and properties were characterized by scanning electron microscope and Fourier transform infrared spectroscopy. The results showed open cell content of polyurethane/chitosan was more than 95% and open cell str...

Risk Assessment of Malachite Green in Food

An Isocratic Toxic Chemical-Free Mobile Phase HPLC-PDA Analysis of Malachite Green and Leuco-Malachite Green

This paper describes a reserved-phase high-performance liquid chromatographic (HPLC) method for detecting malachite green (MG) and leuco-malachite green (LMG) using an isocratic toxic organic solvent/reagent-free mobile phase. Chromatographic separations were performed an Inertsil WP300 C4 with 0.02 mol/L octane sulfonic acid–ethanol mobile phase and a photodiode-array detector. The total run t...

Electrochemical Treatment Of Malachite Green Dye Solution Using Iron Electrode

Present study was performed to investigate the variables that influence the removal efficiency of malachite green (aniline) dye from aqueous solution by an electrochemical (EC) technique. The batch EC studies were performed using iron electrode to evaluate the effect of operating parameters such as pHo and processes parameters such as current density and initial dye concentration. Parameters pH...

An improved malachite green assay of phosphate: mechanism and application.

The classical malachite green (MLG) assay of phosphate, which added MLG after molybdate to the acidified reaction solutions of phosphate, tolerated interference from papaverine, sildenafil, and some similar hydrophobic amines. Resonance Rayleigh scattering signals, the alleviation of interference by poly(vinyl alcohol), and the precipitation of some yellow complexes supported that the irreversi...
