The polymer/zeolite composite net for entrapping ammonia in water

Abstract

Ammonia is an important problem adversely affecting waste water. Various methods for removal of ammonia from waste water have been applied. Among these methods, adsorption by zeolite is considered to be the simplest way. Zeolite can reuse by incubating at high temperatures. However, it is difficult to separate zeolite in large scale water treatment. In this research, the polymer/zeolite composite net for entrapping ammonia in water was studied. The objective was to create the ammonia adsorption net which can be easily used and can be reused. Two composite fibers, CA/Z and PAN/Z, were produced by wet spinning method. The results showed that CA/Z was more capable on ammonia adsorption than PAN/Z and pure Z. The quantity of zeolite in the composite fiber (CA/Z 4:1 and 3:1) were also studied. The results showed that different ratios CA/Z were not statically significant difference in ammonia adsorption efficiency. Finally making the adsorption net experiment was studied. The composite fibers were knitted though the square frame and were tested. The results showed that the nets increased the efficiency of the fibers on ammonia adsorption.
