Characterization of chitosan as a coagulant for heavy metals treatment in turbid seawater using scanning electron microscope (SEM)
Chitosan is a natural polysaccharide that can be derived from deacetylation of chitin which is a natural component obtained from the shell of crustaceans. Chitosan was claimed to have the ability to act as a coagulant to remove water turbidity. Turbid sea water indicate the presence of other element...

| description | Chitosan is a natural polysaccharide that can be derived from deacetylation of chitin which is a natural component obtained from the shell of crustaceans. Chitosan was claimed to have the ability to act as a coagulant to remove water turbidity. Turbid sea water indicate the presence of other element or compound in the sea water which could affect the quality of sea water and disrupt the living of aquatic system. Thus, the purpose of this research were to study the role of chitosan as a coagulant in the treatment of turbid sea water and to study the characteristics of chitosan by using SEM-EDX. The mass of chitosan and turbidity of sea water before and after water treatment were measured and observed respectively. Scanning Electron Microscope (SEM) are used to observe morphology of chitosan and sea water. Energy dispersive X-Ray was used to determine the element presence in the samples. From the data of this research, chitosan only dissolved in hydrochloric acid and showed the highest turbidity removal from sea water of pH 9.0. The morphology of chitosan for pre and post water treatment changed due to the coagulation that occurred. |
