Abstract

Adsorption study of Cr (VI) and Pb (II) from aqueous solution using animal charcoal derived from cow bone

Cow bones (femur and humerus) obtained from Zango abattoir village, Zaria, Nigeria were washed, rinsed with deionized water and sundried for a week. The cow bones were further dried in the oven at 1050C for 72 hours, after which the bones were crushed and calcined in a muffle furnace (model GLM-3+PD/ IND) at 5000C for 30 minutes. The carbonized bone samples were sieved into particle size 355μm using an Endecott’s sieve. Adsorption experiments were carried out at a temperature 300C , three different timings viz: 5, 10 and 20 minutes, and five different initial metal ion concentrations viz: 10ppm, 20ppm, 30ppm, 40ppm and 50ppm of lead and chromium ions were prepared from the standard stock of each metal ion solutions respectively. The adsorbent (cow bone charcoal) was used to investigate the adsorption of lead and chromium from aqueous solution. The effect of initial concentration and adsorption isotherms were studied. The cow bone charcoal exhibited good sorption capacity, and the adsorption data fitted the Langmuir and Freundlich isotherm; and on the basis of the Langmuir constants, the maximum adsorption capacity was observed for lead (1.42) at 300C and 10 minutes, while that of chromium (2.49) was observed at 300C and 10 minutes.
