The aim of this paper was to present the synthesis, characterization and application of the Fe3O4 - chitosan composite as potential adsorbent for removing lead ions from industrial wastewater. The nanocomposite nanomaterial was characterized by XRD and SEM analyzes. The influence of some parameters (pH of wastewater, lead ions concentration and dose of Fe3O4 - chitosan absorbent) upon the efficiency of wastewater treatment were investigated. The Pb (II) ions concentrations in wastewater were 0.5, 1, 1.5 and 2 mg/L. The amounts of Fe3O4 - chitosan nanocomposite adsorbent tested were 0.05, 0.1 and 0.2 g. In some experimental conditions, Fe3O4 - chitosan nanocomposite adsorbent leaded to obtaining of 100% wastewater treatment efficiency.

This study reviewed the most common methods for removing lead ions from industrial wastewater and municipal wastewater. Most of the research done was reviewed using traditional methods such as chemical precipitation, ion exchange, reverse osmosis, oxidation, evaporation, electric-dialysis, membrane filtration, and solvent extraction. These operations were related to several restrictions, that comprised the treatments to be limited to a definite concentration of the Lead (II) ions. Similarly, disadvantages complicated the production of huge quantities of dangerous waste although very high costs. This means these operations were very costly. For these reasons, to utilize the agricultural waste and low-cost adsorbents operation can be considered as eco-friendly. Currently, agricultural waste and natural materials are present in a huge quantity, and that is very damaging to the environment. Therefore, adsorption is an alternate operation for eliminating Lead (II) ions. According to the increased quality of adsorption operations, like the properties of improved adsorptive, increase availability, and cost-effectiveness, the operation is economical option for eliminating Lead(II) ions.

Lead remediation was achieved using simple cost, effective and eco-friendly way from industrial wastewater. Phragmitesaustralis (P.a) (Iraqi plant), was used as anovel biomaterial to remove lead ions from synthesized waste water. Different parameters which affected on adsorption processes were investigated like adsorbent dose, pH, contact time, and adsorbent particle size, to reach the optimized conditions (maximum adsorption). The adsorption of Pb (?) on (P.a) involved fast and slow process as a mechanism steps according to obey two theoretical adsorption isotherms; Langmuir and Freundlich. The thermos dynamic adsorption parameters were evaluated also. The (?H) obtained positive value that meanes adsorption of lead ions was an endothermic processwhile (?G)values were negative which means that adsorption of lead ions was a spontaneous process and the decrease in (?G) with temperature increasing revealed that lead ions adsorption on (P.a) became favorable with temperature increasing

The study presents the possibility of using chlorophyta in the removal of cadmium and lead ions from industrial wastewater produced after the washing of equipment used in the manufacture of battery and batteries. The process was conducted with the use of two algal cultures: Raphidocelis subcapitata produced in laboratory conditions, and a mixed chlorophyta population collected from a natural, eutrophicated water reservoir with heavy metal ions present in the water and sludge. The study showed that the effectiveness of a pure algal culture is comparable to that of a mixed chlorophyta population, characterized by greater diversity of functional groups at binding sites and higher resistance to stress that may occur in the wastewater environment. The maximum effectiveness of ions sorption was 64% for cadmium (mixed algal population) and 60% for lead (Raphidocelis subcapitata).

Biosorption of the lead ions from aqueous solutions using dum palm kernel was studied, the lead ion removal depends on the contact time, pH and adsorbent dosage. The optimum contact time, pH and adsorbent mass with in the experimental limit of this work were 100 minutes, 6-7, and 2.5g/L respectively. The maximum percentage of lead ions removed was 87%. The data fitted well with Temkin and Langmuir models, the regression correlation were obtained to be 0.9660 and 0.8667, respectively. The biosorbent may be economical if developed further for industrial wastewater and natural contaminated water treatment.
