In this study, the date stones/CuFe2O4 nanocomposite was synthesised by a graft of CuFe2O4 nanoparticles on surface stones (DS) for removal rhodamine B (RhB) and methyl orange (MO) from aqueous solutions. The adsorption RhB MO DS@CuFe2O4 shows good agreement with second-order kinetic Langmuir isotherm models. maximum capacity found to be 555.56 03 mg g–1 303.03 MO, respectively. This is spontan...

We have fabricated nanometer-sized channels, demonstrated a technique for the introduction of liquid into the channels, and carried out time-resolved fluorescence measurements of aqueous solutions. In this study, 330-nm- and 850-nm-sized channels were fabricated on fused-silica substrates by fast atom beam etching and hydrofluoric acid bonding methods. A liquid introduction method utilizing cap...

Due to the pollution of dyeing and textile industry wastewaters in different colors and the need to remove these pollutants from the wastewaters, it is necessary to study and develop effective and efficient technology solutions required. To remove dye from aqueous solutions, photodegradation is employed as an effectively simple way. Thus, the BiOBr photocatalyst was chemically made by synthesis...

Multixenobiotic resistance (MXR) is an important mechanism of cellular efflux mediated by ATP binding cassette (ABC) transporters that bind and actively remove toxic substrates from the cell. This study was the first to identify ABC transporter P-glycoprotein (P-gp/ABCB1) as a representative of the MXR phenotype in earthworm (Eisenia fetida). The identified partial cDNA sequence of ABCB1 overla...

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...

Saat ini, penggunaan bahan kimia berbahaya sebagai tambahan pangan (BTP) masih menjadi masalah besar bagi Indonesia. BTP yang marak digunakan oleh produsen jajanan adalah boraks, formalin dan rhodamine-B. Banyak kasus keamanan kurang terjamin ditemukan di lingkungan sekolah dengan konsumen terbanyak siswa. Penelitian ini bertujuan untuk melakukan identifikasi ketiga serta menganalisa pengetahua...

Tracer tests represent a well-established method for delineating key environmental processes in various media and engineered systems. Tracers like Rhodamine B WT are frequently applied due to their strong fluorescence even at low concentrations.. However, lack of ecotoxicological data, limit values these tracers cannot be determined. This study fills this critical data gap by providing ecotoxic...

In the present work we describe the structure and the spectroscopic characterization of a spirocyclic derivative of a rhodamine B ligand whose properties allow discrimination of light-up effects induced by metal ion chelation and variation of pH. Distinction of the two effects is important for the use of this type of ligand to detect and monitor metal ions in aqueous solutions. The synthesis of...
