Abstract

Hydroxyapatite (HAp) is the most stable form of calcium phosphate and is widely applied in the medical field because it’s properties is similar to the components in certain organs of the human body such as bones and teeth. The aims of this study were to synthesis hydroxyapatite from duck egg shell by precipitation method, studied the effect of Ca/P molar ratio and stirring speed on the hydroxyapatite product and compare the result for such variable. Synthesis HAp was done by three steps. First step was calcination duck eggshell to CaO. Second step, made PCC (Precipitated Calcium Carbonate). Third step, synthesis HAp used precipitation method. Variables used were molar ratio Ca/P 1.67;1.77;1.87 and stirring speed 200, 250, 300 rpm. HAp product was analized by FTIR, XRD, SEM-EDX and BET.

Abstract

Pollution by domestic waste is not only produced from residential areas nevertheless is also produced by attempt in tourism especially lodging facilities and infrastructure such as hotels. One of the effects is the wastewater that produced by the hotel. The hotel wastewater treatment using membranes by ultrafiltration is an easy and effective way. The fabrication of silica membranes is also assisted by supporting materials that is compound by Polyvynil Alcohol (PVA) and Polyethylene Glicol (PEG). In this researches the synthesis of silica membranes with variations composition of the silica mass 8, 10, and 12 gram. The aim of this researches is to learn the effect of variations composition of the silica mass on the membranes synthesized towards separation of the BOD5, COD, and TSS that contained in hotel wastewater. The deflation level of BOD5, COD, and TSS were done by passing hotel wastewater through the silica membranes which is synthesized. The optimum coefficient of silica membranes rejection for deflation level is BOD5, COD, and TSS repeatedly are 72,12%; 79,09% and 87,61% along the value of flux that produced is 22,562 L/m2.Hour. The getting larger composition of silica membranes, then the measure and tightness of the membranes pore that produced are getting bigger and organized along with the coefficient of rejection (%) will also decrease.Keywords : flux and rejection, hotel wastewater, membrane, silica, ultrafiltration.

Abstract

Zeolite 4A can be used as alternative for replacing phosphate as builder of detergen. It can be synthesized from calcined kaolin. Kaolin in its natural state is less reactive and difficult to form zeolite 4A, threfore kaolin needs to be activated through calcination process. Calcination of kaolin were studied in variation of temperatures from 500˚C, 600˚C, 700˚C, and 800˚C. Sodium aluminate and sodium silicate used as reactants in reaction process of synthesis zeolite 4A mixed in 1, 2 and 3 hours, then heated at 80˚C for 8 hours. The samples were characterized by infrared spectroscopy. A calcination temperature of 700˚C ~ (2 hr) is the optimum for this kaolin to change into a reactive metakaolin which gives zeolite 4A with high crystallinity.                             Keywords: calcination, kaolin, metakaolin, synthesis, zeolite 4A
