SYNTHESIS, CHARACTERIZATION AND APPLICATIONS OF ZEOLITE FROM KAOLIN AND RICE HUSK ASH FOR THE ADSORPTION OF COPPER AND CHROMIUM METALS IN WASTE WATER OF ELECTROPLATING INDUSTRY
Zeolites made from Bangka clay and Karawang rice husk ash were synthesized through the reaction between sodium silicate and sodium aluminate with the volume ratio of 25:25:50 (K4) and 50:25:25 (K6).Expand
Leaching of Iron and Zinc into Food Simultant from Tin Can Packaging
Cans are widely used as primary packaging in various food products. Ferrous (Fe) and zinc (Zn) metal as the constituent components in the manufacture of can packaging bodies can experience corrosionExpand
Validation Method of Flame-AAS with Microwave Digestion for Mineral Analysis in Carbohydrate-Rich Samples
One of the effective methods for mineral destruction is by using microwave digestion. However, some parameters in the microwave manual book are different with AOAC method such as the volume of acid,Expand

Removal of Cu Metals from Wastewater by Adsorption using Synthetic Zeolites from Rice Husk and Corncob
Heavy metals, such as Cu, are hazardous components so that it needs to reduce their concentration due to their negative impact on the environment. One method that can be used to reduce heavy metalsExpand
Validation of Mineral (Fe, Zn, and Cu) Analysis Methods in Carbohydrate, Protein and Fat-Rich Samples Using Microwave Digestion Method
Destruction process using both dry and wet conditions serves as a significant step in mineral quantification. Wet destruction using microwave-assisted digestion refers to the standard method of AOACExpand
Equilibrium and Kinetic Study of Removal Copper(II) from Aqueous Solution Using Chicken Eggshells: Low Cost Sorbent
The research aims to investigate feasibility eggshells as potential adsorbent to remove copper(II) ions from aqueous solution. Eggshells powder was characterized using X-ray diffraction, scanningExpand
