Abstract This study aimed at the valorization of abundant and underutilized Casuarina equisetifolia fruit waste (CEFW) biomass as an intact easily separable biosorbent for treatment dye-polluted water. The CEFW was chemically modified to improve its selective biosorption MB, or simultaneously remove MB MO. H 2 O increased surface functional groups, created pores, enhanced MB. CTAB introduced qu...

background and purpose: cadmium is hazardous and non-biodegradable material entering the food chain. in this paper, the removal of cadmium from aqueous solutions by sunflower powder (the natural biosorbent) was investigated. materials and methods: the experiments were performed in a batch system. the effect of parameters such as contact time, ph, cadmium concentration and adsorbent dose were ev...

The use of biosorbents for heavy metal removal has revealed enormous potential of algae for biosorption. The dried biomass of Spirogyra hyalina was used as biosorbent for removal of cadmium (Cd), mercury (Hg), lead (Pb), arsenic (As) and cobalt (Co) from aqueous solutions atdifferent initial concentrations of the heavy metals and contact time of the biomass. The results showed that highest amou...

Mycotoxin adsorption onto biomaterials is considered as a promising alternative for decontamination without harmful chemicals. In this research, the adsorption of B-aflatoxins (AFB₁ and AFB₂) using Pyracantha koidzumii biomasses (leaves, berries and the mixture of leaves/berries) from aqueous solutions was explored. The biosorbent was used at 0.5% (w/v) in samples spiked with 100 ng/mL of B-afl...

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...

Selenium (Se) is a contaminant in effluents from coal mines and coal-fired power stations, where it is encountered as the oxyanion selenate (SeO4(2-), hereafter Se(VI)). Se(VI) can be removed from solution with Fe-treated biosorbents, but the efficacy of these treatments in effluents with multiple contaminants is unclear. This study investigates the interactions between Se(VI) and the oxyanions...

The mining industry generates huge amounts of wastewater, containing toxic heavy metals. Treatment to remove heavy metals is necessary and recent work has been focused on finding more environmentally friendly materials for removing heavy metals from wastewater. Biosorption can be an effective process for heavy metal removal from aqueous solutions. Our objectives were to investigate the removal ...

Liquid wastewater is essentially the water disposal of community after pure has been used in a variety applications. In recent years, heavy metal concentrations, besides other pollutants, have increased to reach dangerous levels for living environment many regions. Among metals lead most damaging effects on human health. It can enter body through uptake food (65%), (20%) and air (15%). With thi...

The residue derived from the alginate extraction S. filipendula was applied for biosorption of aluminum aqueous medium. adsorptive capacity (RES) completely evaluated in batch mode. effect pH, contact time, initial concentration, and temperature assessed through kinetic, equilibrium, thermodynamic studies. biosorbent characterized prior post-Al by N2 physisorption, Hg porosimetry, He pycnometry...
