Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
Recovery and Recycling of Silver from Residual Solution Derived from Determination of Chemical Oxygen Demand
(Brazilian Chemical Soc, 2015-07-01)
Analytical methodologies that generate wastewater rich in potentially recoverable silver ions are commonly used to determine chemical oxygen demand (COD). The chemical residue resulting from these assays is classified not ...
