This research aims to develop Wood Plastic Composites （WPCs） from rice hull and poly（vinyl chloride）（PVC）. The in- fluences of the rice hull particle size and content on the mechanical properties and the visual appearance of the WPC decking board were investigated. The experimental results revealed that the impact strength tended to decrease with increasing rice hull content. The composites with larger particle sizes exhibited higher impact strength. Under tensile and flexure load, higher rice hull content induced greater modulus and ultimate strength when the rice hull was applied at less than 60 phr. Beyond this concentration, the modulus and the strength dropped due to the formation of rice hull agglomerates. The smaller particles of the milled rice hull, the greater tendency there was for them to act as a pigment to form a darker shade close that of the rice hull on the composite decking board. The larger particle sizes were 106 μm and beyond simply embedded in the white PVC matrix.

Diclofenac is an ecotoxic pharmaceutical compound affecting both aquatic and terrestrial ecosystems even at low *** this study,batch adsorption experiments were conducted to remove sodium diclofenac(SD)from aqueous solutions using rice hull biochar(RHB)*** SD removals were obtained with increasing initial SD concentration,RHB dosage,contact time,and decreasing initial *** studies revealed that Langmuir isotherm best fitted the experimental data with the highest coefficient of determination for both pH 2(R2=0.9827)and pH 7(R2=0.9460).For kinetic studies,the pseudo second-order model gave R2=0.9999 for both pH 2 and pH *** removals reached up to 97%at pH 2 and up to 80%at pH *** SD removals were achieved at solution pH lower than the adsorbent pHpzc since electrostatic repulsion was ***-transform infrared analysis showed the major involvement of C=O in the adsorption *** study demonstrated the potential of using agricultural residues such as rice hulls for the treatment of wastewater contaminated with pharmaceutical compounds.
