Iron-modified zeolite as a sorbent for nitrate and phosphate removal from water systems
The discharge of effluents bearing nitrogen and phosphorus into the water body causes the eutrophication phenomenon, which leads to restrictions in the use of water sources. Different physical, chemical and biological methods have been developed and applied for their removal. Recent scientific investigations have been focused on the application of abundant naturally occurring low-cost materials, such as natural zeolites and their modifications that allow for the removal of anionic species. This paper has focused on the investigations of the feasibility of iron- modified zeolite (IMZ) as a sorbent for nitrates and phosphates from water solutions. The influence of the initial pH and concentration of the solution on sorption efficiency of nitrates and phosphates on IMZ has been investigated. Higher removal efficiency of phosphates has been observed on IMZ than on nitrates. It has been found that phosphates and nitrate removal efficiency depends on the point of zero charge of the material and the pH of solutions. The additional benefit of the IMZ application in phosphate and nitrate removal is the possibility of subsequent use of saturated IMZ as a fertilizer.
