TLDR
Batch sorption proved to be more efficient than the column sorption and hence batch sorption was used to remove Cr(VI) from a textile dyeing industry wastewater and the phytotoxic effect of treated and untreated wastewater was studied against Zea mays.About:

Standard methods for the examination of water and wastewater
TL;DR: The most widely read reference in the water industry, Water Industry Reference as discussed by the authors, is a comprehensive reference tool for water analysis methods that covers all aspects of USEPA-approved water analysis.
Journal ArticleDOI
The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

Standard methods for the examination of water and waste water.
TL;DR: Alkalinity measurements are used in the interpretation and control of water and wastewater treatment processes and can be interpreted in terms of specific substances only when the chemical composition of the sample is known.

Vigor Determination in Soybean Seed by Multiple Criteria1
TL;DR: In this article, a multiple criteria approach is presented by which vigor was evaluated in 16 lots of soybean (Glycine max L., cv. ‘Lee-68’) seed by determining O∂ uptake, CO₂ production, uptake of labeled glucose or leucine, conversion of isotopes into ¹ ₂ and polysaccharides or proteins, and leaching of metabolites through membranes of excised embryonic axes after 5 hours of imbibition.
