ABSTRACT
Industrial wastes and wastewaters such as those produced by petrochemistry, metal plating, fertilizers, and pesticides were the main sources for discharging the toxic ions in the environment [1,2].
The most common toxic ions in wastewaters responsible for particular problems were heavy metal ions, azo dyes, etc. [3-5]. Despite the fact that the human body needs small dose such as Zn2+, an excess of it may cause eminent health problems such as depression, lethargy, neurological signs, and increased thirst. Exposure to such toxic ions can cause health problems such as liver or kidney damage, Wilson disease, insomnia, cancer, diarrhea, nausea, vomiting, dermatitis, chronic asthma, coughing, and headache [6-11].
