Use of Mediterranean plant as potential adsorbent for municipal and industrial wastewater treatment

  A batch adsorption system using dried Carpobrotus edulis plant as a new cheap adsorbent was investigated to remove some pollutants from raw wastewater. The results show that the uptake of nitrate, phosphate and some heavy metals ions from wastewater by C. edulis increased with increasing contact time. The percentage uptake of heavy metals from industrial wastewater...

Polyamine levels and pigment contents in rapeseed regenerated in vitro in the presence of zinc

  The present work was designed to select hyperaccumulator plants by in vitro breeding from transversal thin cell layers. The thin layer explants of Brassica napus cv. Jumbo were cultivated directly in the presence of ZnSO4 at different concentrations (0.1 to 1 mM). Regenerated shoots were transferred into pots, acclimatized, and cultured in the greenhouse. After 3 weeks, the...

Chelate-assisted phytoextraction of metals from chromated copper arsenate (CCA) contaminated soil

  This study examined the effect of citric acid and ethylenediaminetetraacetic acid (EDTA) application on As, Cr and Cu phytoextraction of maize (Zea mays L.) plant in chromated copper arsenate (CCA) contaminated soil. The soluble and available metal pools in the contaminated soil were determined to be 6.20 ± 0.12 mg/kg and 9.80 ± 0.39 mg/kg As; 34.70 ± 1.10 mg/kg and 69.80...

Algal density assessed by spectrophotometry: A calibration curve for the unicellular algae Pseudokirchneriella subcapitata

  The unicellular algae Pseudokirchneriella subcapitata (Korschikov) Hindák has been frequently used for ecotoxicological tests. In this paper, a calibration curve is proposed correlating absorbance values (684 nm) and cell density for routine ecotoxicological experiments. Density (cells/mL) could be estimated as follow: Cell Density = e {[ln (absorbance_684)...
