Fluorescence Excitation−Emission Matrix Regional

2003121&ensp·&enspExcitation−emission matrix (EEM) fluorescence spectroscopy has been widely used to characterize dissolved organic matter (DOM) in water and soil. However, interpreting the >10,000 wavelengthdependent fluorescence intensity data points represented in EEMs has posed a significant challenge. Fluorescence regional integration, a quantitative technique that integrates the volume

Analytical Methods of Isolation and Identifiion

The chemical constituents of plants are complied, and monomeric compounds must be obtained via extraction and isolation before structure identifiion, bioactivity screening, and so on. In recent years, the new technologies and methods of the extraction, isolation, and structural identifiion have come forth, which promote the speed of extraction and analysis of phytochemicals.

Immobilization of Metal Hexacyanoferrate IonExchangers

2015827&ensp·&enspMetal hexacyanoferrates are very efficient sorbents for the recovery of alkali and base metal ions (including radionuclides such as Cs). Generally produced by the direct reaction of metal salts with potassium hexacyanoferrate (the precursors), they are characterized by ionexchange and structural properties that make then particularly selective for Cs(I), Rb(I) and Tl(I) recovery (based on

US Patent Appliion for BIOCHAR WATER TREATMENT

Diatomite, perlite and cellulose are common materials used as filter aids. Although diatomite is the most widely used filter aid, many organic materials, such as potato starch particles, cotton fibers and solid polymers, are also used. The char and ash from combustion of some biomass materials such as rice hull can be used as a filter aid.
