This study attempted to fill epoxy, a widely used industrial material, with pumice, cheap volcanic rock, in order form composite material. The objective was evaluate the worth of pumice and improve mechanical properties epoxy. Composite samples no filler, 10%, 20%, or 30% filler were produced. An ultrasonic mixer during manufacture made sure powder dispersed properly, vacuuming stopped air pock...
Abstract In this study, pumice from different regions of Turkey (Diyarbakir, Southeast and Bitlis, East Turkey) has been supplied used as supporting material for nanoscale zero-valent iron (nFe 0 ). Native Bitlis (NBP)-supported (BP-nFe ) native Diyarbakir (NDP)-supported zero-value (DP-nFe were synthesized under the same conditions. (NDP, NBP) pumice-supported nFe BP-nFe adsorbents morphologic...
Background and Objective: Chemical dyes used in the textile wastewater besides having harmful effect on the environment, have carcinogenic and mutagenic effects. Methylene blue has harmful effect on living organisms in short period of exposure. The goal of this study was optimization of the catalytic ozonation process by pumice modified by magnesium nitrate in removal of methylene blue dye ba...
Pumice quarried by LAVA MINING AND QUARRYING SA from Yali Island, Dodecanese, is used in domestic and foreign markets mainly as concrete lightweight aggregate, masonry unit constituents, road substrate, loose soil stabilization. It a porous natural volcanic rock with low density, thermal noise transmission, the highest strength among all or artificial materials of mineral origin. Nowadays, pumi...
