Removal of Ni(II), Zn(II) and Co(II) from Aqueous Solutions by Using Different Types of Activated Carbon
The adsorption capacity of activated carbon and activated carbon with amide group towards Ni(II), Zn(II) and Co(II) from aqueous solutions was studied in varying treatment conditions such as contact time, weight of sorbent, pH and initial concentration of treated metal ions. The adsorption capacity was investigated by batch experiments. The results showed that the removal percentages were enhanced by increasing the weight of the added sorbent, contact time, pH of the solution and the initial concentration of treated metal ions. The optimum order of increasing removal percentages of metal ions by using activated carbon (AC) prepared from sawdust of beech wood at pH=5, with an initial concentration of metal ions of 100 mg/L, and after two hours of shaking, was: Zn(II)
期刊介绍:
Portugaliae Electrochimica Acta is a bi-monthly Journal published by the Portuguese Electrochemical Society since 1983. Portugaliae Electrochimica Acta publishes original papers, brief communications, reviews and letters concerned with every aspect of theory and practice of electrochemistry, as well as articles in which topics on history, science policy, education, etc. in the electrochemical field (teaching or research) may be discussed.
