Brownish water color, low pH, and high content of Fe and Mn metals are obstacles in direct utilization of peat water. Peat water treatment can be done by the adsorption method. The stages of this study began with the preparation of the adsorbent by dripping Na-alginate solution into a variety of CaCl2 solution concentrations. Furthermore, the adsorption of peat water was carried out by batch method with variations in the contact time and mass of the adsorbent to get the adsorbent with the highest % removal. The optimal contact time for Fe and Mn adsorption on peat water is 6 hours. The optimal % removal value for the influence of Fe adsorption contact time for Ca-alginate variations of 0.1 M and 0.2 M CaCl2 solution were 20.38% and 21.19%, respectively. The optimal % removal value for the influence of Mn adsorption contact time for Ca-alginate variations of 0.1 M and 0.2 M CaCl2 solution were 30.98% and 41.37%, respectively. The optimal mass of adsorbent for Fe and Mn adsorption in peat water is 0.75 g. The optimal % removal value for the influence of Fe adsorption mass adsorption for Ca-alginate variations of 0.1 M and 0.2 M CaCl2 solution were 79.28% and 21.67%, respectively.

Using coagulant/flocculants based on natural polymers were many used due to many available, renewable source, and environment friendly. One of that coagulant/flocculants was chitosan that can be produced through deacetylation of chitin. Amino groups in the chitosan structure play important role in the coagulant/flocculants process. The aim of research is using chitosan-based coagulants in the coagulation-flocculation of kaolin suspension. In here, there were two coagulants type, first, single coagulant which chitosan with different molecular weight  added alone in kaolin suspension. Second, mix coagulants which chitosan aid with alum in kaolin suspension. As the result, functional group analysis showed that chitosan with different molecular weight have the same functional groups. Increasing molecular weight of chitosan increase NH2 groups and degree of deacetylation. The removing turbidity of kaolin suspension showed that increasing molecular weight chitosan increase removing turbidity of kaolin suspension. Using double coagulant (chitosan and tawas) have the removing turbidity greater than single coagulant.","PeriodicalId":31725,"journal":{"name":"Jurnal Kimia Mulawarman","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49668226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
