Boric Acid Post-Modified [Al]ZSM-5 Zeolites: Properties, Acidity, and Ethanol/Ethene Conversion. [PDF]

Chemistry
The modification of MFI zeolites with boric acid leads to the formation of framework boron, unstable surface species, and unbound deposits. Relevant BAS for catalysis and access to pores are strongly reduced. The boric acid is removed upon converting C1 or C2 alcohols and ethene. ABSTRACT The effect of boric acid post‐modification on [Al]ZSM‐5 zeolites

Chemiluminescent ELISA for the BTEX Determination in Water and Soil

Analytical Sciences, 2010
An indirect competitive chemiluminescence enzyme-linked immunosorbent assay (CL-ELISA) for the determination of benzene, toluene, ethylbenzene, and ortho-, meta-, para-xylenes (BTEX) in soil and water was developed. The assay was optimized concerning the coating conjugate concentration, anti-BTEX antiserum dilution, incubation time effect on primary ...
