Larrea tridentata, or creosote bush, is a common desert plant that inhabits the Chihuahuan Desert. Due to its great abundance and high growth tolerance of heavy metal-contaminated soils, it was chosen as the primary candidate for this study. Previous experiments conducted on inactivated and untreated sodium hydroxide (NaOH) Larrea tridentata leaf tissues showed that it effectively bound metal i...

A comparative research has been developed for acidity and stability constants of M(TTA) and M(Asp) complexes which have been determined by potentiometric pH titration. Depending on metal ion–binding properties, vital differences in building complex were observed. The present study shows that in M(TTA) complexes, metal ions are coordinated to the carboxyl groups, but in M(Asp) some metal ions ar...
