Application of nanotechnology in removal of NAPLs from contaminated aquifers: a source clean-up experimental studySpringer Science and Business Media LLC - Tập 20 - Trang 427-433 - 2018
Tannaz Pak, Nathaly Lopes Archilha, Raaid Al-Imari
This work investigates the removal of non-aqueous phase liquids (NAPLs) from
groundwater resources using nanotechnology. We present results of a series of
multiphase fluid displacement experiments conducted in a naturally occurring
sandstone rock. These experiments involve injection of an aqueous suspension of
silica nanoparticles to remove a trapped NAPL phase. Specifically, the effect of
nanopar... hiện toàn bộ
Combined advanced oxidation and biological treatment of tannery effluentSpringer Science and Business Media LLC - - 2011

During leather processing in tanneries, considerable amount of wastes with
organic and inorganic pollutants are generated. For removal of these pollutants
and recovery of water, biological treatment methods and reverse osmosis (RO)
based membrane technologies are adopted. While recovering water from treated
tannery effluent using RO membranes, presence of residual organics, dye
molecules, and othe... hiện toàn bộ
Tanning performance and environmental effects of nanosized graphene oxide tanning agentSpringer Science and Business Media LLC - Tập 18 - Trang 1997-2006 - 2016
Shenghua Lv, Qingfang Zhou, Ying Li, Yaya He, Haoran Zhao, Shiyu Sun
Nanosized graphene oxide (GO) with multiple oxygen-containing groups was
prepared as a leather tanning agent. Leather tanned with 0.4 % GO can meet the
shrinkage temperature (T s) and mechanical properties required for the
commercial leather products. The GO nano-tanning effluent had much lower
pollution indexes, such as total nitrogen, total organic carbon, chemical oxygen
demand, biochemical oxy... hiện toàn bộ
Marginal abatement costs for GHG emissions in Canada: a shadow cost approachSpringer Science and Business Media LLC - Tập 25 - Trang 1323-1337 - 2022
Samuel Gamtessa, Monika Çule
This study approximates the marginal abatement costs (MACs) of reducing GHG
emissions in Canada using the shadow cost approach. Utilizing industry level
data, we are the first to offer Canadian estimates based on a Hyperbolic Output
Distance Function (HODF) and the stochastic frontier estimation. Accounting for
GHG emissions caused by energy consumption, we obtain an average shadow MAC of
$130/t a... hiện toàn bộ
