Batch leaching tests were employed to investigate the leaching potential of arsenic (As) and selenium (Se) from two fly ash samples. The effect of pH and solid-to-liquid (S/L) ratio on As and Se leaching was examined in this preliminary study. Maximum As leaching occurred at pH 7-8, and soluble As concentration slightly increased with decrease of S/L ratio. Se displayed consistently increasing ...

Poorly water-soluble compounds are difficult to develop as pesticide products and face great challenges in water-based and environmentally friendly formulation development. In this study, high pressure homogenization combined with lyophilization was adopted to prepare the solid nanodispersions of chlorantraniliprole with poor solubility and high melting point. The mean particle sizes of the sol...

Solid dispersions have been widely used to enhance the solubility of poorly water soluble drugs. In this study, solid dispersions of valsartan (VAL) with natural polymers such as hupu gum (HG), guar gum (GG) and xanthan gum (XG) were prepared by kneading technique in the weight ratios of 1:1,1:2,1:3 and1:4.The prepared solid dispersions were investigated by X-ray diffraction, infrared spectrosc...

Background and Objectives: Fast proteolysis of cheese in ripening process may lead to the premature attack of casein, release of the majority of enzymes into the whey, and loss of cheese composition from curd to whey. In this study, the effect of liposomal Flavourzyme on proteolysis of Iranian white brined cheese, as well as on the yield and composition of whey and curd was investigated. Mater...

INTRODUCTION Prednisolone is a class II substance according to the Biopharmaceutics Classification System. It is a poorly water soluble agent. The aim of the present study was to improve dissolution rate of a poorly water-soluble drug, prednisolone, by a solid dispersion technique. METHODS Solid dispersion of prednisolone was prepared with PEG 6000 or different carbohydrates such as lactose a...

Total soluble solid (TSS) content is commercially used as fruit quality index because of its high positive correlation with sugar content. In the present study, The effect of foliar application of naphthalene acetic acid (NAA) with different concentrations (0, 25, 50, and 100 mg.L-1) at 4 true leaf and fruit set stages and plant training (pruning and thinning) on TSS and soluble sugar (i.e. suc...

Asparagus is a vegetable with high antioxidant activity. In this research, asparagus juice was produced from fresh asparagus macerate treated with a carbohydrases mixture (Viscozyme) at 37 degrees C for up to 8 h. Rutin content, antioxidant activity, yield, soluble solid content, and color of the produced asparagus juice were determined. The results showed that Viscozyme significantly increased...

BACKGROUND The purpose of this study was to develop a novel silymarin-loaded solid nanoparticle system with enhanced oral bioavailability and an ability to provide excellent hepatic protection for poorly water-soluble drugs using Shirasu porous glass (SPG) membrane emulsification and a spray-drying technique. METHODS A silymarin-loaded liquid nanoemulsion was formulated by applying the SPG me...
