Abstract

Seawater contains large amounts of cations. Since this resource is abundant and cheap, it can be a laudable source of plant nutrients. The objective of this study was to investigate the extent to which zeolite could sorb and desorb nutrients in different concentrations of seawater. Results indicated that Zeolite sorbed Na and Mg. The highest percentage of Na and Mg sorbed was 76.19 and 36.69%, respectively obtained for 10% seawater. The desorption study indicated that the higher the seawater concentration used during the sorption, the higher the Na and Mg desorbed. Passing diluted seawater through zeolite leached out K and Ca to the extent that the effluent was concentrated with the cations. This by-product solution can be used as a source of plant nutrients. However, high concentration of such cations in the solution caused high pH and EC, which means that the solution has to be diluted to meet the requirements of plants.

Abstract

Zeolites are crystalline, hydrates of alumino-silicate mineral with a three-dimensional framework structure which are occured in Indonesia as large deposits in the form of near-pure minerals and of low cost. In recent years, many scientist have focused their research to develop these minerals to be used in science and technology applications. Because of their unique crystal structure, zeolites have the importance properties of sorption, ion-exchange, molecular sieving and catalysis, which enable to them to be used in various industrial processes, waste management and environmental pollution problems. This paper describes the prospect of clinoptilolite and mordenite, which have been investigated in many laboratories, to be considered for their utilization in the industries and environmental management.

Abstract

Nowadays, ceramics world has been developing into what the interior, building exterior, industries and household. The quality and its ability made by certain specification which compatible with the structure, design and the function. For example, the building structure that usually has high humidity whether indoor or outdoor will need certain ceramics for the floor to keep on dry condition, unslippery, clean while fungus will not live. For that purpose stone ceramics that made by natural zeolite will has same characters as natural zeolite function such us absorb/release water reversibly, absorb smelt or volatile compound, molecular filter. The making of zeolite ceramic was done at certain burning temperature where natural structure of zeolite will not be destructed or collaps and forming amorphous compound. So the natural zeolite function will preserve. The development of composite is made from natural zeolite as the main ingredients which clay, kaolin, and feldspar are used as binders. In order to decrease burning temperature, natrium compound added into the composite and the experiment done at temperature 800-1000 oC with composite pressure between 50-100 kg/cm. the result of experiment indicate that on burning temperature 800oC whether with using SEM or XRD analysis, zeolite is in mordenite crystal form. Whereas at burning temperature 1000oC, the crystal structure of zeolite has been destructed and forming albit and calcian as new compound. The zeolite ceramics which formed at 800 oC, with pressure at 50 kg/cm has strong and compact characters with absorption ability up to 23%.
