Wastewater from many sectors that contains hazardous organic pollutants exacerbates environmental contamination. Consequently, outstanding photocatalytic substances can successfully degrade are needed to provide pollution-free water. From this perspective, zinc oxide/g-C3N4-based composites desirable due their low cost, strong reactivity, and friendliness. So, in the current investigation, sequ...

A mesoporous activated carbon (MAC) was synthesized from waste tires rubber (WTR) via a one-step ZnCl2/FeCl3 activation route, and the typical sample implemented in eliminating Eriochrome Black-T (EBT) dye Cr(VI) their synthetic effluents. The impact of impregnation ratio ZnCl2/FeCl3, temperature, period optimized . best AC created at 750°C for 60 minutes using 2:1 ZnCl2/FeCl3:WTR ratio. This a...

A semiautomatic procedure for the direct estimation of both serum calcium and magnesium is described. The indicator used, Eriochrome blue SE (EBSE), has the advantage of stability and freedom from interference by naturally occurring substances. The procedure requires 3-5 mm. per sample and is very reproducible. The values obtained agree with those obtained by back-titration of excesschelator an...

Background: It has long been recognized that the presence of azo metal complex dyes and their non-complexed counterparts in wastewaters, which is due to manufacturing use textile industries, renders natural waterways intensely coloured, therefore aesthetically unacceptable. Azo dye moieties are also known be precursors human carcinogenicity. Objective: This work aimed at decolourisation metal-a...

Antasida merupakan obat penetral asam lambung yang digunakan untuk membantu mengatasi gangguan pencernaan penderita gastritis. Uji mutu fisik dan penetapan kadar dijadikan parameter mengetahui suatu obat. Penelitian ini bertujuan memastikan magnesium hidroksida pada antasida bermerek dengan nomor batch berbeda sesuai spesifikasi. dilakukan meliputi uji keseragaman ukuran, bobot, kerapuhan, keke...
