This research focuses on understanding biosorption process and developing a cost effective technology for treatement of heavy metals-contaminated domastic water. A new biosorbent has been prepared by crushing of neem leaves. The experiments were designed according to Taguchi’s (L16) orthogonal array to optimize experimental runs. In order to assess the biosorption behavior of neem leaves satisf...

Biosorption is a process in which solids of natural origin are employed for binding heavy metals. It is a promising alternative method to treat industrial effluents, mainly because of its low cost and high metal binding capacity. In this work, the mercury and iron biosorption process by Sargassum sp. seaweed biomass was studied. The work considered the parameters of mercury and iron sorption su...

Biosorption has been defined as the property of certain biomolecules (or types of biomass) to bind and concentrate selected ions or other molecules from aqueous solutions. As opposed to a much more complex phenomenon of bioaccumulation based on active metabolic transport, biosorption by dead biomass (or by some molecules and/or their active groups) is passive and based mainly on the "affinity" ...

Biosorption is an alternative to traditional physicochemical means for removing toxic metals from ground and wastewaters. Biosorption of Pb(II) ion from solution was studied using Bacillus cereus M116 immobilized in calcium alginate gel in batch mode, and optimum conditions were determined. The experimental results showed that the immobilized bacterial strain was effective in removing Pb(II) io...

<p>The majority of nitrate (NO3‾) pollutants come from a different type industries. Even if present in low amounts, these nitrates are harmful to humans and aquatic systems. This research investigated the utilisation Tamarind Fruit shell (TFS) as biosorbent removal Nitrate aqueous solution. TFS was modified by soaking it with distilled water. Many remediation strategies available, but the...
