Nano-structured calcium silicate as sorbent in a study of artificial mining waste
Nano-structured calcium silicate can adsorb a wide variety of ionic species. The mechanism of the uptake observed depends on the nature of the species and is selective towards the more insoluble hydroxides for cationic and insoluble calcium compounds for anionic sources. Additionally, waterborne solids can become trapped, with the silicate, acting as a filter. Artificial mining waste samples have ...

Removal of chromium(III) from water samples by a low-cost sorbent: application to a mixture of chromium(III) and chromium(VI)
Adsorption of Cr(III) and Cr(VI) ions from aqueous solutions and water samples has been investigated using Powdered Marble Waste (PMW). The effect of solution pH, initial metal concentration, sorbent dose, shaking time, temperature, and foreign ions on the adsorption of Cr(III) was studied. It was found that the sorption capacity increased with the increase of Cr(III) concentration and ...

Analysis of US EPA Method 8270D Semivolatiles Using a 30 m x 0.25 mm I.D., 0.50 μm SLB-5ms
Application Note 401: US EPA Method 8270D specifies a procedure for the determination of semivolatiles in solid waste and ground water samples. The long list of analytes includes compounds of a variety of functionalities. A 0.25 μm df column is commonly used for this method, as it will allow for a short analysis time. However, the thin phase film of this dimension limits its sample capacity. ...

Movement of toxic metals from small-scale industrial areas: a case study from Delhi, India
In India, an estimated 70% of the total industrial pollution load is attributed to Small and Medium Enterprises (SMEs). Among SMEs, small-scale industries continue to use obsolete technologies with no stringent rules for pollution control. Consequently, waste generated from them is generally dumped without treatment. These facts are strengthened from the analysis conducted on solid waste and ...
