Abstract:
This study investigates the use of sawdust from 3 hardwood species as lowcost adsorbent for the removal of copper from contaminated water. The experimental design used for this study was 3 x 2 x 4 factorial experiment; the different sawdust species, two baselines (treated and untreated) and four levels of pH and time as factors were combined and used for the study. Test was carried out to investigate the effect of sawdust pretreatment on their adsorption capacity in the removal of Copper ions from contaminated water at different pH levels; the sawdust samples were sieved through a screen size of 850 ?m after which a portion of each species sawdust was subjected to pretreatment by boiling while the other portions were maintained as control samples (untreated). The results show that adsorption capacity for both treated and untreated samples were 69.75±13.78%, 68.60±19.48%, 69.34±23.08%, 74.79±17.79%, 74.52±22.30% and 76.90±18.21% for Alstonia boonei, Erythrophleum suaveolens and Ficus mucuso respectively. The contact time and pH showed no significant difference between the treated and untreated samples. Sawdust from the selected wood species are suitable to be used as adsorbent towards the removal of copper from contaminated water.

Publication Title:

Abstract:
The knowledge of density and anatomical features of wood is required to understand its morphology prior to its use in order to recommend appropriate treatments and application. Anatomy of coconut wood with its density was investigated in this study. Methods used include sectioning and fibre characterization both along and across the stem of the tree. The mean results obtained for the Fibre Length, Fibre Diameter, Lumen Width and Vessel Diameter were 1.49mm, 0.030mm, 0.02mm, and 0.27mm in that order. Its density was found to vary along the stem. The basic density distribution of Cocos nucifera showed that the middle portion has the highest density of 1107.85kg/m3, followed closely by the base portion with 1052.67 kg/m3 while the top portion recorded the least density of 1003.79 kg/m3. Both the density and anatomical results showed a comparable value which make it a suitable alternative for timber.

Abstract:
The study was undertaken to evaluate the combustion properties of briquettes from wood and agricultural wastes. Terminalia superba sawdust and banana leaves were used and cow dung acting as binder in varying mixing ratios. The briquettes were produced using an automatic press at a constant compaction pressure of 1.77kN/m2 and the substrate were combined at ratios 5:1:4, 4:4:2, 3:2:5, and 2:5:3, the briquettes produced were subjected to combustion tests. Combustion related properties such as percentage volatile matter, percentage ash of the briquettes was determined. The compressed density ranged between 517.09 ± 35.40kg/m3 and 571.29 ± 28.73kg/m3, while the reduction in density which signifies the rate at which the briquettes reduced in density after compression and relaxation ranged between 46.82±2.56 kg/m3 and 55.81±1.80kg/m3 respectively. The result from this study shown that briquette in ratios of 2:5:3 and 3:2:5 show better combustion properties than others.
