Remediation of hexavalent chromium contaminated water through zero-valent iron nanoparticles and effects on tomato plant growth performance.

ABSTRACT: Contaminated water with hexavalent chromium Cr(VI) is a serious environmental problem. This study aimed to evaluate the Cr(VI) removal by zero valent iron nanoparticles (nZVI) reduction process and the impact of Cr(VI), nZVI and combined treatment with nZVI and Cr(VI) on tomato growth performance. To evaluate the Cr(VI) toxic effect on germination capability, seeds were exposed to increasing Cr(VI) concentrations up to 1000 mg L^-1. The inhibition of seed germination and the decrease of hypocotyl and root length started from Cr(VI) 5 mg L^-1. Under treatment with Cr(VI) + nZVI 5 mg L^-1, seed germination, hypocotyl and root length resulted significantly higher compared to Cr(VI) 5 mg L^-1 treatment. The impact of only nZVI was investigated on chlorop
