Removal of inorganic mercury from aqueous solutions by biomass of the marine macroalga Cystoseira baccata.
The ability of Cystoseira baccata algal biomass to remove Hg(II) from aqueous solutions is investigated. The mercury biosorption process is studied through batch experiments at 25 degrees C with regard to the influence of contact time, initial mercury concentration, solution pH, salinity and presence of several divalent cations. The acid-base properties of the alga are also studied, since they ...
متن کاملEquilibrium and kinetic study on chromium (VI) removal from simulated waste water using gooseberry seeds as a novel biosorbent
Gooseberry seed (Phyllanthus acidus) was used as an adsorbent to determine its feasibility for the removal of Cr(VI). Various parameters such as pH, temperature, contact time, initial metal concentration and adsorbent dosage were investigated to determine the biosorption performance. Equilibrium was attained within 60 minutes and maximum removal of 96% was achieved under the optimum co...
متن کاملOptimization, Equilibrium and Kinetic Studies of Basic Red 2 Removal onto Waste Gossypium hirsutum Seeds
Cationic dye - basic red 2 (BR2) was removed from aqueous solutions by sulfuric acid activated waste Gossypium hirsutum seeds (WGSAB). The main and interactive effects of five process variables such as, adsorbent dose (1.25 – 5 g/L), initial dye concentration (100–300 mg/L), contact time (1–3 h), pH (2 – 12) and temperature (20 – 400C) were investigated via response su...
متن کاملMozambique Tilapia Fish Scales as Potential Biosorbent for Zn and Pb Ions Removal: Kinetic and Isotherm Studies
The toxicity and presence of heavy metals in wastewater pose environmental-disposal problems because of their non-biodegradability and persistence in the environment. Heavy metals in wastewater were removed by using physical, chemical and biological treatment. Biosorption is one of the biological treatments emerging as an alternative environmental friendly technology for the removal of metal io...
متن کاملBatch Removal of Acid Blue 292dye by Biosorption onto Lemna minor: Equilibrium and Kinetic Studies
Background; Recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. Therefore, the aim of this study was to determine the feasibility of using Lemna minor for Acid Blue 292 (AB292) dye removal from aqueous solution and to determine the optimal conditions. Methods; This experimen...
