Moringa oleifera, a tree indigenous in tropical and sub-tropical areas, has been widely used in water purification in many low-income regions such as Africa, India, and Asia. Its seeds are known to contain proteins that possess coagulating and antimicrobial properties but its use in water treatment is compromised by the corelease of soluble organics in the seeds. These organics can serve as foo...

This study selected solid wastes, such as rice husk ash (RHA), inactive Saccharomyces cerevisiae powder (ISP), and rice husk (RH), as the potential adsorbents for the removal of Fe(II) and Mn(II) in aqueous solution. The structural characteristics, functional groups, and elemental compositions were determined by scanning electron microscope (SEM) and Fourier translation infrared spectrum (FT-IR...

Penelitian ini menggunakan material dari limbah Rice Husk Ash (RHA) sebagai bahan susbtitusi semen dan Bottom (BA) substitusi agregat halus pada campuran beton.

Hasil hari diperoleh nilai rata-rata berturu...

The objective of this study was to determine effect of germination on total anthocyanin content (TAC) and antioxidant activity of colored rice (Oryza sativa L). The normal, non-waxy rice variety Phitsanulok 2 was used as a control and two pigmented rice including black glutinous rice (local name Niew Dam), and black non-waxy rice (local name Hom Nil) were used in this study. Rough rice and dehu...

The rich husk is an agricultural waste of rice cultivation worldwide, which highly in amorphous silica. Rice obtained from Dagiri was pyrolysed at 750 ? to give white ash (RHA) further treated with acid (ARHA). reacted sodium hydroxide 90 for 2 hours 30 min produce Sodium silicate crystals. silicates synthesized the study were characterized some physicochemical parameters. Their structural and ...
