Heavy metals are discharged into aquatic environment and causes serious problems to the
environment, human's health, and other organisms. The industrial effluents contain high …

A basic requirement of colorimetric sensors is that they must allow the analyte to access the
chromophores. This study elucidates the fundamental sensitivity of membrane morphology …

SO 2 and NO x emission into the environment will harm the environment and health. In
recent years, the research of biological processes for purifying SO 2 and NO x is very …

Mining has led to severe environmental pollution in countries with exhaustive mining
production and inadequate industrial waste regulation. Microorganisms in contaminated …

A stable and relatively long lifetime optical membrane sensor for determination of heavy
metal ions was prepared by covalent immobilization of dithizone (DTZ) on cellulose acetate …

Non-viable biomass of Pseudomonas putida immobilized in agar–agar was used as
adsorbent to remove aluminum from aqueous solutions. In batch assays, adsorption …

In this study, removal of copper from synthetic aqueous solution was done using adsorption
process. The batch study was done at room temperature and analyzed using Freundlich and …

In the present study, a laboratory-scale biofilter column was designed and fabricated. It was
packed with a mixture of coal and compost as a packing medium. The column was enriched …

The principles of gas-phase biofilter systems, modeling, and operations are quite different
from liquid-phase biofilter systems. Because of “biofilter” terminology used in both gas and …

Water pollution by Cr is challenging due to its high toxicity. Most of chromium is released by
industrial processes. Different methods have been developed to remove heavy metals from …
