The clay used taken from Lontor Village, Central Maluku Regency, Banda Besar Island. The clay was activated at 350 °C for 3 hours using a furnace. This study aims to determine the effectiveness of physically activated Lontor natural clay in reducing level... see more

This study aims to determine the effect of calcination temperature on Titanium dioxide impregnated Ouw Natural Clay (LAO) on the degradation of Rhodamine B dye. The calcination temperature used was 200, 300, and 400 °C. Their radiation was carried out wit... see more

Determination of surface acidity on the natural and synthetic montmorillonite clays has been carried out using the acid-base titration method to count the number of bound acid sites per gram of clay. The total acidity of natural and synthetic montmorillon... see more

This study aims to obtain the optimum ratio of Ouw Natural Clay  (LAO):Chitosan in the manufacture of chitosan-LAO composites. The composite will be used as an adsorbent for heavy metals Lead (Pb) and Cadmium (Cd). LAO-Chitosan composites were made w... see more

Clay is a mineral particles composed of silica-alumina base frame, has a layered structure and a hollowed space causing surface becomes very widespread and effective as an adsorbent. Adsorbent of clay is very effective to adsorb cation for having negative... see more

This study was conducted to determine the role of thermal treatment on the crystallinity and pore characteristics of porous ceramic, which was prepared from natural clay (NC) and chitosan (CS) biopolymer using the gel casting method. CS was used as an env... see more

In this work, sorbents based on natural zeolite (Z) and chamotte clay (ChC) treated with NaCl and HNO3 solutions were obtained to extract Na+ and K+ ions from saline water. The physicochemical characteristics of the obtained sorbents were studied by SEM, ... see more

The interactions between clay-plates and hydrophilic polymer are investigated assuming that the polyethylene glycol (PEG) chains are grafted onto face-to-face clay-plates. Besides the usual van der Waals attractive interaction, the clay-plates experience ... see more

In Algeria, inappropriate soils with high plasticity and low bearing capacity are commonly encountered, it was therefore necessary to improve these soils using mineral additives in order to make them acceptable for construction. However, various forms of ... see more
