<p>Fly ash, solid waste from coal-fired power plant, had been utilized as raw material for porous geopolymer by alkaline activation and addition of hydrogen peroxide (H2O2) blowing agent. Porous higher surface area total pore volume compared to fly ash without agent, namely 45.511 m2 g-1 0.05131 cc g-1, respectively. was applied adsorbent anionic dyes Eriochrome Black T (EBT) cationic Met...
In the present work, adsorption behavior of Eriochrome Black T (EBT) on waste hemp activated carbon (WHAC) was examined. The surface WHAC modified by H3PO4 acid treatment. and structural characterization adsorbents carried out using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) analysis. effect influential parameters (pH, contact time, dosage, initial concen...
Battling infection is a major healthcare objective. Untreated infections can rapidly evolve toward the condition of sepsis in which the body begins to fail and resuscitation becomes critical and tenuous. Identification of infection followed by rapid antimicrobial treatment are primary goals of medical care, but precise identification of offending organisms by current methods is slow and broad s...
The Schwartzenbach titration of calcium and magnesium has been applied principally in the field of determination of total hardness in water (1-4). Due to its particular application in this field where many contaminants are possible, Diehi, Goetz, and Hach have published a table of the principal interfering substances, their maximum tolerated concentrations, and the various inhibiting reagents w...
The appearance of kits for the determination of micro amounts of calcium stimulated our interest in the use of Eriochrome Blue SE for this analysis. A study of spectrophotometric curves indicates that, at pH values above 13.7, calcium will complex and cause a change of dye absorbance while magnesium does not complex with the dye. A differential spectrophotometric technic is described in this pa...
