Biomass derived from Tamarindus indica partially activated seed coat was investigated for the removal of nitrate ions from aqueous solutions. Batch experiments were performed to evaluate the parameters like pH, contact time, sorbent dose and initial nitrate concentration. pH of the solution played vital role. The maximum sorption observed at pH=7, sorbent dose 300mg, contact time at 120min, ini...

in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...

OBJECTIVE To investigate the potential of Gomphidius viscidus, a kind of ectomycorrhizal fungi, for phytoremediation of anthracene in soil. METHODS Absorptioe changes of micro-habitat were studied in detail. CONCLUSION Ectomycorrhizal plants have a strong potential for remediation of polycyclic aromatic hydrocarn characteristics of both active and inactivated mycelia. RESULTS A high calcu...

In this article, we used Sargassum hystrix algae as biosorbent for removal of Fe (II) from aqueous solutions that was collected along the Persian Gulf coastline, Bushehr, Iran. The concentration level of remaining Fe (II) in the samples was measured by using flame atomic absorption spectrometry (FAAS, Varian AA240, Australia). The isotherms, kinetics and modeling data of Fe (II) biosorption ont...

The biosorption process of a lypophilised cell suspension of Aspergillus niger was studied for selenite ( − 2 3 SeO ) removal from acid mine drainage in the Sarcheshmeh porphyry copper mine. The biomass was first characterised by the potentiometric titration, and the major ionic content was evaluated. The experimental data suggest that the biomass cell wall contains two main acidic groups with ...

There is a growing need for the use of low-cost and ecofriendly adsorbents in water/wastewater treatment applications. Conventional adsorbents as well as biosorbents from different natural and agricultural sources have been extensively studied and reviewed. However, there is a lack of reviews on biosorption utilizing industrial wastes, particularly those of food processing and pharmaceuticals. ...

The nonylphenol (NP) biosorption and desorption potential for fungal biomass used under batch conditions was investigated using kinetics and isotherm models. Fungal biomass of Rhizopus arrhizus TISTR 3610 exhibited preferential uptake of NP, an endocrine disrupting chemicals. Sporangiospores, asexual spores, were immobilised in chitosan beads. The biosorption data of NP on the moist heat inacti...

ADSORPTION OF COPPER(II) BY PEANUT HULLS IN A FIXED-BED, CONTINUOUS FLOW COLUMN Tyler Stephen Cook, Masters of Science in Chemistry Western Carolina University (April 2017) Advisor: Dr. Carmen L. Huffman Heavy metal pollution is an important concern due to its adverse health and environmental effects. Biosorption is a way to remove heavy metals from aqueous systems with the use of biomaterials....

Aquatic bryophytes are frequently used as biomonitors for trace metals in aquatic ecosystems. Nevertheless, their special characteristics also allow using them as biosorbents to clean industrial wastewaters. As biosorption is a low cost and effective method for treating metal-bearing wastewaters, understanding the process kinetics is relevant for design purposes. In this study, the ability of t...

Indian jujuba seed powder (IJSP) has been investigated as a low-cost and an eco-friendly biosorbent, prepared for the removal of Acid Blue 25 (AB25) from aqueous solution. The prepared biomaterial was characterized by using FTIR and scanning electron microscopic studies. The effect of operation variables, such as IJSP dosage, contact time, concentration, pH, and temperature on the removal of AB...
