Researchers conducted research into the strength properties of a Geopolymer produced from eggshell powder, bauxite, and flyash with RGL (Reaction generating liquid) cure for 84 days at ambient temperature. Also studied were changes in products Morphology, XRD, FTIR studies SEM images microstructure. The results indicated that, various mix proportions, gradually improved 28 to days. aged Geopoly...

A simple, rapid, cost-effective spectrophotometric method is developed to determine arsenic in ppm levels. The present study is based on the reaction of arsenate with acidified molybdate and vanadate to form a molybdovanadoarsenate complex. The heteropoly acid complex formed interacts with cationic dye, Rhodamine B resulting in pinkcoloured ion-pair complex whose absorbance is measured at 590 n...
