Understanding Laboratory Wastewater Tests: I. ORGANICS

The COD test uses a chemical (potassium dichromate in a 50% sulfuric acid solution) that “oxidizes” both organic (predominate) and inorganic substances in a wastewater sample, which results in a higher COD concentration than BOD concentration for the same wastewater sample since only organic compounds are consumed during BOD testing.

Distribution Characteristics of Valuable Elements, Al, Li

Apr 16, 2019· The distribution of valuable elements, including aluminum (Al), lithium (Li), and gallium (Ga), and rare earth elements (REE) in the samples was investigated. Results indicate that the contents of SiO2 and Al2O3 in sized ash particles decreased as the particle size decreased; meanwhile, the contents of CaO, SO3, and Fe2O3 apparently increased.
