Otostegia persica biomass as a new biosorbent for the removal of lead from aqueous solutions

Biosorption characteristics of Pb(II) ions from aqueous solution were studied using some residues of solvent-extracted Otostegia persica known as goldar residue biomass. The effects of contact time (0–120 min), the initial pH 3–8, biomass dosage (0.53–2.6 g/L) and the initial lead concentration (5–25 mg/L) on biosorption were investigated. The maximum adsorption capacity of 17.3 mg/g at pH 5.5,...

Myxococcus xanthus biomass as biosorbent for lead.

This paper deals with lead biosorption by Myxococcus xanthus biomass in which dry biomass, accumulating up to 1.28 mmol of lead g(-1), is demonstrated to be a more efficient biosorbent than wet biomass. Dry biomass biosorption was found to be very rapid, reaching equilibrium after 5-10 min. Culture age, the initial lead concentration and pH affected this process, but temperature did not. Furthe...

Application of Azolla Filiculoides biomass for Acid blue 15 dye (AB15) Removal from aqueous solutions

Background: one of the most important environmental pollutants is industrial wastewaters. Discharging of colorful industrial effluents to receptive waters can lead to eutrification and it has the carcinogenic and mutagenic properties. Therefore, the aim of this study is evaluation of Acid blue 15 dye removal by dried Azolla from aqueous solution. Material and methods: The Azolla biomass was dri...

Preparation of Nanochitosan as an Effective Sorbent for the Removal of Copper Ions from Aqueous Solutions

The most important pollutants in wastewater are heavy metal ions. In this paper, the effects of various parameters such as pH, contact time, initial concentration, and temperature on the adsorption of Cu (II) by nanochitosan (NCS) was investigated in batch experiment. Nanochitosan was prepared based on ionic gelation and charac­terized by means of Fourier Transform Infrared Spectroscopy (FTIR),...

Removal of Lead (II) Ions from Aqueous Solutions onto Activated Carbon Derived from Waste Biomass

The removal of lead (II) ions from aqueous solutions was carried out using an activated carbon prepared from a waste biomass. The effects of various parameters such as pH, contact time, initial concentration of lead (II) ions, and temperature on the adsorption process were investigated. Energy Dispersive X-Ray Spectroscopy (EDS) analysis after adsorption reveals the accumulation of lead (II) io...
