A highly ordered two-dimensional hybrid magnetic nanocomposite has been prepared by synthesizing and intercalating a new cationic aluminum-hydroxy ferric ferrocyanide compound into a cation-adsorbing nanoclay (montmorillonite). Chemical and structural properties were investigated by X-ray diffraction, transmission electron microscopy, thermogravimetric and differential thermal analyses, Fourier...
Methylene blue (MB) is a typical cationic dye, causing significant color changes in water bodies even small dissolved amounts, as well affecting the survival of neighboring plants and...
fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...
Konsumsi zat warna sintetik sangat besar karena biasa digunakan di berbagai jenis industri seperti tekstil, kosmetik, makanan, kertas, karpet dan plastik. Keberadaan tersebut lingkungan yang berasal dari limbah cair dapat membahayakan kesehatan manusia. Penelitian ini menguji kemampuan pasir sungai dalam mengadsorpsi warna. Digunakan dengan pertimbangan ketersediaan melimpah harga murah. Lima d...
Methylene blue is a cationic thiazine dye useful in staining parathyroid glands during surgical resection. There have been a number of reports of altered neurologic status postoperatively in patients who are taking antidepressant medications when they received methylene blue for their surgery. We present a case report and review 30 additional cases that have been reported in the literature. It ...
this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...
Optimization of the Methylene Blue Assay for Anionic Surfactants Added to Estuarine and Marine Water
The existing rapid method for the determination of anionic surfactants in aqueous solutions relies on the association of the cationic methylene blue dye with the anionic surfactant to form an electroneutral complex that is subsequently extracted into chloroform and determined spectrophotometrically. This methylene blue active substance (MBAS) assay suffers from salt interference in estuarine an...
Negative charged sites in the normal rabbit articular cartilage were investigated using cationic colloidal iron methods. In light microscopy of the cartilage stained with the colloidal iron at pH 1.5, a distinct Prussian blue reaction was observed in the pericellular matrix, and a weak blue reaction in the territorial and interterritorial matrices. At pH 7.0, a diffuse Prussian blue reaction wa...
Highly stable and homogeneously dispersed amino acid coated silver nanoparticles (ANP) of ≈ 10 nm diameter, ranging from 420 to 430 nm are prepared on AgNO3 solution addition to gum of Azadirachta indica solution at 373.15 K. The amino acids were selected based on their polarity. The synthesized nanoparticles were characterized by UV-Vis, FTIR spectroscopy, HR-TEM, XRD, SEM and 1H-NMR. The coat...
Intercalation products based on ionic exchange reaction between cationic dye methylene blue and Na-montmorillonite were prepared. Montmorillonite particles intercalated with methylene blue were characterized using X-ray diffraction, infrared spectroscopy, elemental and thermo-gravimetric analysis. The results showed that intercalation of dye molecules within the interlayer spaces of montmorillo...
