Study on Adsorption of Cu and Ba from Aqueous Solutions

Sep 09, 2018The wild herbs used in this study were purchased from a perfumer. The dried herbs were then cut into small pieces and milled to a powder using a laboratory planetary ball mill (DECO-PBM-V-0.4 L). The powders were sieved into particles of 50, 100, 200, 300, and 400 μm using an Octagon D200 digital sieve shaker. The adsorbents were stored in

Effect of finasteride particle size reduction on its

Feb 16, 2018Introduction. Size reduction is a process of decreasing the large or coarse solid drug particles into small or fine unit masses. This process represents a potentially useful way for enhancing the bioavailability of hydrophobic drugs especially when particles in the nano-size range have been developed (Wang et al., 2013).Improving drug bioavailability due to size reduction is attributed to the
