KINETIC STUDY OF ADSORPTION OF HEXAVALENT CHROMIUM IN AQUEOUS SOLUTION USING BAY LEAF (LAURUS NOBILIS) AS NEW BIO-ADSORBENT
2018-10
International conerence on advance science and engineering
_ Laurus nobilis (Bay leaf), was examined for its capacity to remove hexavalent chromium Cr(VI) poisonous, from aqueous solution. The bio-adsorbent using bay leaf obtained from Laurus nobilis was investigated in batch experiments. The influence of main parameters such as chromium concentration, pH and shaking time are tests. The effect of beginning concentration of Cr(VI) ion (10 to 50 mg/dm ), pH (1 to 6) and shaking time (5 to 180 min) have been reported. The optimum pH was found to be pH 4.. Results show that the most appropriate model was pseudo second-order kinetic and it correlate with the trial statistics well.

Enhanced Photoelectrochemical Water Splitting of Hydrothermally- Grown ZnO and Yttrium-doped ZnO NR Arrays
2018-08
1ST International Conference on Materials Engineering & Science (IConMEAS 2018)
Abstract. Undoped and Y doped ZnO nanorods (YZO NRs) were prepared by hydrothermal
method. The as-prepared ZnO and YZO NRs with different Y/Zn molar ratios were used as
anodes for electrochemical water splitting. Then, photoelectrochemical (PEC) water splitting
performances of YZO NRs were tested. When compared with pristine ZnO NRs, the
photocurrent density generated with yttrium doped zinc oxide NR as electrode was higher(1.2
mA cm-2 ) than that obtained with pristine ZnO NRs (0.25 mA cm-2), at 0.2 V vs. Ag/ AgCl
using samples of 1.2 mol % of yttrium. This performance corresponds to calculated photoconversion
efficiency of 0.40%, at a low potential (-0.38V vs Ag/AgCl) of the non-doped ZnO
NR film.
