Removing Malachite Green and Leucomalachite Green From Freshwater and Seawater With Four Water Treatment Agents

Malachite green (MG) residue in aquatic environments can adversely affect food chains. To solve this problem, many adsorbents have been developed to remove MG from aqueous solutions. These exhibit benefits different aspects such as low cost, nontoxicity, and environment friendliness. Zeolite, oyster shell powder (OSP), humic acid (HA), Chloride dioxide (ClO 2) are widely used agents for water purification, indicating their potential both freshwater seawater. Liquid chromatography tandem mass spectrometry was performed a valid analytical method measuring its metabolite leucomalachite (LMG). The analysis examined linearity, specificity, accuracy, precision, limit of quantification. We found that three agents—zeolite, OSP, HA—have high affinity LMG seawater because physicochemical properties; ClO 2 exhibited even greater efficiency degradation due oxidation capacity. removal zeolite, OSP HA 100%, 87.52%, respectively. In the MG-containing seawater, 95.24%, 6.57%, 89.36%, 53.56%, while 62.70%, 84.65%, treatments expressed 100% efficiency. adsorption capacity decreased order: zeolite = > OSP; seawater: OSP. Whereas LMG-containing study, four treatment reported reducing amount hazardous environments.
