Biosorption of Zinc(II) and Copper(II) Ions from Aqueous Solution by Pericarps Oak Acorns

Ions from Aqueous Solutions by Biosorption Processes

Due to the disadvantages of heavy metal removal from aqueous sytems by conventional methods, alternative new methods have been investigated lately. Biosorption is one of these new methods. In this method, metal ions are transported into cell structure, and removal is ensured by several mechanisms that occured between living or non-living microorganisms and metal ions. The metal removal, the use...

Biosorption of Cd(II) and Ni(II) Ions From Aqueous Solution by Raw and Pre-Treated Cystoseira Indica Algae

Biosorption of Cu(II) Ions from Aqueous Solution by Red Alga (Palmaria Palmata) and Beer Draff

In this study, the ability of red alga (Palmaria palmata) and beer draff (brewery waste) for Cu(II) removal was investigated. The influence of factors, such as pH, initial copper concentrations, and contact time, were also studied. Results showed the adsorption process was strongly dependent on the pH value and initial concentration. The optimum pH value was in the range of 5-6. The Langmuir is...

Biosorption of Fe(II) and Mn(II) Ions from Aqueous Solution by Rice Husk Ash

Rice husk ash (RHA), an agricultural waste, was used as biosorbent for the removal of Iron(II) and Manganese(II) ions from aqueous solutions. The structural and morphological characteristics of RHA and its elemental compositions before and after adsorption of Fe(II) and Mn(II) were determined by scanning electron microscopic (SEM) and X-ray fluorescence (XRF) analyses. Batch experiments were ca...

Biosorption of Copper Ions from Aqueous Solution by Flammulina velutipes Spent Substrate

To remove heavy metals from aqueous solution and reclaim valuable materials from mushroom byproducts, Flammulina velutipes spent substrate (FVSS) was developed as a novel biosorbent for copper ion removal. Batch experiments demonstrated that ion removal was pH-, biosorbent dosageand initial metal concentration dependent. The maximum removal capacity of 15.56 mg/g was achieved at pH 6.0 with a b...
