Effect of biomass containing zinc metal at different operating parameters on gasification efficiency.

This paper describes the effect of Zn on the gas production of a fluidized-bed gasifier to determine the relationship between Zn and the gasification process. Different concentrations of Zn were used in the preparation of artificial waste to elucidate the effect on gas product composition, gas product heat value, gas production rate, and H2 yield in the gasification process. Zn served to increase H2 generation during the gasification process.

Phytoremediation of Cr(III) by Ipomonea aquatica (water spinach) from water in the presence of EDTA and chloride: effects of Cr speciation.

Wastewater is often co-contaminated with chromium, chelating agents, and chloride. Influences of Cr(3+) speciation on Cr phytoremediation by Ipomonea aquatica were investigated. MINEQL+ was employed to estimate Cr speciation.
