Zeolites are used in water purification; removal of hazardous metal ions; removal of organic pollutants from wastewater; removal of ammonia, nitrogen, and phosphates from wastewater; applications in gas treatment; adsorption of volatile organic compounds (VOC); CO2adsorption; adsorption of other gases;...
heavy metal resistant bacterial strains is very rare in this field. Against this background, the present work aims to investigate the physiological and biochemical effects ofB. aeriusandB. cereusstrains on spinach grown in soils contaminated with heavy metals. The novelty of this work lies in the...
Venus and Earth have several things in common. Both are terrestrial planets composed of silicate minerals and metals that are differentiated between a rocky mantle and crust and a metal core. Like Earth, Venus orbits within our Sun’s circumsolarhabitable zone(HZ), though Venus skirts the inner...
