ABSTRACT. In this work, an activated carbon composite made with magnesium oxide nanoparticles (MgONP-AC) was effectively utilized for methyl orange (MO) adsorption. The effect of pH (6-10), mass MgONP-AC (0.1-0.3 g/L), initial MO concentration (10-30 mg/L), and temperature (283-323 K) on removal investigated using a central rotatable experimental design based the response surface technique (RSM...

BACKGROUND Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day(-1) per hen of three coloured carrot varieties (orange, yellow and purple) as forage material in comparison with a standard feed control on egg production, egg yolk colour and deposition of carot...

rosine B, Tartrazine, Lissamine Green B, Pyronin G, Acetyl Yellow G, Ponceau 6R, Ponceau SX, Food Orange #2, and Food Yellow #3. The concentration of dye tested was 50 mg/ L of incubation mixture (25 pg/tube) in RIA systems for human lutropin (hLH), its alpha and beta subunits, rat LII, rat corticotropin (rACTH), rat insulin, and human thyroxin (T4) and testosterone. (For T4 we usedthe MAGIC-T4...

The alcoholic fermentative ability of yeast strains; Saccharomyces cerevisiae (isolated from yam), S. cerevisiae (from sugarcane molasses), S. carlsbergensis (from sugarcane molasses) and S. cerevisiae var. ellipsoideus (from orange juice) were examined on orange juice (Citrus sinensis). The quality of the wine produced on the basis of the acidity, ash content, vitamin C and the alcohol content...

In this study, we have successfully constructed Ag3PO4/Ag/g-C3N4 heterojunctions via the hydrothermal method, which displays a wide photo-absorption range. The higher photocurrent intensity of indicates that separation efficiency photogenerated electron–hole pairs is than both Ag3PO4 and Ag/g-C3N4 pure substances. It confirmed efficient attributed to heterojunction material. Under visible light...

Drying characteristics and quality attributes are greatly dependent on the maturity status of fresh fruits. Hence, this work investigated changes in volatile properties mangoes at ripening stages (from lowest to highest degree—RS-1, RS-2, RS-3, RS-4) during infrared drying. Results showed that total soluble solids/titratable acid, texture, nutrient composition (phenolic, vitamin C, ?-carotenoid...

This study examines the sorption of methylene blue on the cheap unconventional bio sorbents, citrus fruits: oranges and lemons. Bio sorbents which was used was: orange and lemon peel, seeds and pulp. The results are compared with results of sorption to mineral sorbents, zeolite clinoptilolite, Pyrolox and Birm. Sorption kinetics and the influence of pH on the sorption of methylene blue on orang...
