Silica functionalized with sulfonic acid catalyst (SiO2-SO3H) was synthesized through a one-pot method and evaluated as the catalyst material for esterification of levulinic acid in an excess amount of ethanol. Sodium silicate solution was used as the sil... see more

In this research, interaction occurring in adsorption process between Cd(II) and active site of diatomaceous earth has been studied. The study was carried out by evaluating Cd(II) adsorption on diatomaceous earth at various pHs, either for the earths with... see more

Two novel materials of 2-aminobenzimidiazole (AB) and 1-(o-tolyl)biguanide (TB) modified silicas coated on the iron sand magnetic material (MM@SiO2/AB and MM@SiO2/TB) have been synthesized and were used to adsorb Au(III) from Au/Cu/Ni solution. Silica lay... see more

In this research magnetite was synthesized by coprecipitation method, in which solution of NH4OH was added into the solution containing a mixture of Fe2+/Fe3+ (molar ratio 1:2) until pH 11 under strong ultrasonic agitation for 30 min. The black sediment o... see more

In this research, magnetite coated with L-arginine modified silica (Fe3O4/SiO2-GPTMS-Arg) has been synthesized through a sol-gel process at a room temperature in two Routes. In Route 1, a precursor of sodium silicate solution (source of SiO2), 3-glycidoxy... see more

This research was motivated by the researcher's interest in the level of self-esteem possessed by students in the student activity unit. This article aims to describe and analyze the self-esteem profile of students according to the type of student activit... see more

Abstrak. Penelitian ini bertujuan untuk membuat kalsium karbonat terendapkan atau precipitated calcium carbonate (PCC) dari cangkang kerang mutiara melalui pelarutan dengan larutan HNO3, karbonasi dengan karbondioksida, dan sonikasi. Cangkang kerang denga... see more

Abstrak. Penelitian ini bertujuan untuk mengekstraksi dan memunikan silika dari abu sekam padi (ASP) dan melihat karakteristik silika yang dihasilkan apabila diberi perlakuan sonikasi dan refluks. Metode yang digunakan dalam penelitian ini adalah sol-gel ... see more

Zinc Layered hydroxide (ZLH) is a layered material easily synthesized with a structure identical to brucite-like material. Due to the exchangeable anions in the interlayer compensating for the positive charge of a brucite-type layer, ZLH provides a wide a... see more
