Have exposed individual drink sips of water. Seek medical the removal of methyl violet 2B cationic dye. Afterpreparation, the obtained composite was characterized by applying several instrumental techniques, includingX-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and determination of pH at the point of zero charge. The adsorption of MV on CF/poly(NIPAM-co-AAc) reflected pH-dependence and pH 7.0 was the optimum pH value for MV adsorption. Adsorption isotherms at 293, 313 and 333 K could be described by Langmuir, Freundlich, Temkin and Sips models, amongst which Langmuir model had the best R2 values.

Yellow . Methyl yellow . 2.9 ∼ 4.0 This study reported Nepenthes rafflesiana pitcher (NP) and Nepenthes rafflesiana leaves (NL) as new adsorbents for methyl violet (MV) dye. The experiments were done using 2 h contact time and without any pH alteration (pH 4.4). The effects of pH and ionic strength revealed hydrophobic-hydrophobic interaction as the predominant force of dye interaction with the adsorbent. Both NP-MV and NL-MV Pengaruh pH pada methyl violet dan methylene blue Dua puluh miligram mg abu daun bambu dimasukkan ke dalam larutan methyl violet 20 mg/L dengan variasi pH 5; 7; 9 dan 11 dengan waktu optimum yang didapatkan menggunakan shaker kecepatan pengadukan 200 rpm.
