3. Use and Manufacturing3.1 Definition ChEBI: A one-carbon compound substituted by 4 bromo groups. 3.2 Description Carbon tetrabromide, with the chemical formula CBr4, has the CAS number 558-13-4. It appears as a colorless solid with a sweet odor. Its basic structure consists of four ...
Wet desulfurizationPhysical adsorptionTaking advantage of the solubility of H2S and insolubility of CH4in some special solutions (e.g., methanol, sulfoxide) to remove H2S Chemical adsorptionOne of the oldest methods for H2S removal involves alkaline solutions scrubbing to form compounds ...
Carbon is the fourth-most abundant chemical element on Earth, after hydrogen, oxygen, and helium [1], [2], and it is considered as a base element for building organic compounds that are essential for life, such as proteins, carbohydrates, nucleic acids, and lipids. This element drives whole...
It interacts with a specific analyte through its bio-recognition element [6]. A wide range of samples can be tested with biosensors, including body fluids, food samples, and cell cultures. The main features of biosensors include: (a) being highly specific for the analyte, (b) reaction must...
The initial concentrations of the solutions varied between 10–500 mg⋅L−1 for benzene and its derivatives, and between 10–50 mg⋅L−1 for the drugs, for the equilibrium tests. The concentrations used were selected to be representative of the concentration range of organic compounds in...
