Sequential spectrophotometric determination of chromium(III) and chromium(VI) using flow injection analysis
(1985-12-01)
A flow injection analysis (FIA) procedure for the speciation of Cr(III) and Cr(VI) using the 1,5-diphenylcarbazide (DPC) method is presented. As Cr(III) does not interfere in the Cr(VI) - DPC reaction, both Cr(VI) and total ...

Reduction of total chromium levels from raw tannery wastewater via electrocoagulation using response surface methodology
(Polish Society of Ecological EngineeringPL, 2019)
This study focused on reducing total chromium levels in raw wastewater from the leather tanning industry via electrocoagulation to comply with maximum permissible limits (MPL) and to determine the effects of main process ...
Preconcentration and speciation of Cr(III) and Cr(VI) in water samples using amberlite XAD-16 resin and determination by flow injection-flame AAS
(Perkin-Elmer Corporation, 2002-03)
A method for the pre-concentration and speciation of chromium was developed. On-line pre-concentration and determination were obtained using flame atomic absorption spectrometry (FAAS) coupled with flow injection (FI). To ...
In Vitro Effect of Molasses Concentration, pH, and Time on Chromium Removal by Trichoderma spp. from the Effluents of a Peruvian Tannery
(MDPI Open Access JournalsPE, 2023-05-19)
The effluents generated by the tannery industry have a high content of chromium and other toxic elements, representing a potential threat to ecosystems. An eco-friendly alternative to treat these effluents is the use of ...
The removal of the trivalent chromium from the leather tannery wastewater: the optimisation of the electro-coagulation process parameters.
(IWA PUBLISHING, 2011-02-01)
The capacity of the electro-coagulation (EC) process for the treatment of the wastewater containing Cr3+, resulting from a leather tannery industry placed in Medellin (Colombia), was evaluated. In order to assess the effect ...
