Phytoremediation: Data on effects of titanium dioxide nanoparticles on phytoremediation of antimony polluted soil

Abstract

This data article presents effects of titanium dioxide nanoparticles (TiO2 NPs) on phytoremediation of antimony contaminated soil using S. Bicolor in detail. Seedlings of S. bicolor were exposed to different doses of TiO2 NPs (0,50,100,250,500 and 1000 mg/kg) in plastic pots containing Sb-contaminated soil and cultivated over a 80-day period in a greenhouse. Harvested plants were dried in an oven at 70 °C for 48 h to obtain dry weight of the biomass. The concentrations of metal(loid)s in soil as well as in plant organs were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). Chlorophyll contents of fresh leaves materials were measured by UV spectrophotometry at 645 nm and 663 nm. Data on distribution of Sb and Ti in roots and shoots of S. bicolor contaminated soil treated with different levels of TiO2 NPs are indicated in tables. Figures presented the data on plant growth behavior, Sb and Ti accumulation capacities, and physiological response of S. Bicolor in various treatments. The presented data are beneficial to gain insight into phytoremediation potential of S. bicolor in Sb-contaminated soil as well as plant behavior under the stress of both Sb and TiO2 NPs in soil. These data are useful for environmental researchers, soil and plant scientists, nanotechnology experts, stakeholders and decision-makers involved in soil decontamination challenges.
