Fig. 10From: Zingiber officinale rhizome extracts mediated ni nanoparticles and its promising biomedical and environmental applicationsa Percent degradation of Ni-NPs with time, the degradation ability of nanoparticles increases and reaches its maximum at 160 min and b) its UV–visible experimental spectra. The absorbance decreased with time as the dye degraded. In pristine form, crystal violet dye gave an absorbance peak at 580 nm, but with time, the absorbance intensity decreasedBack to article page
