This research work is aimed at decolourizing gum Arabic using activated charcoal so as to improve the quality of gum Arabic before the use of additives on the gum Arabic. The experiment was conducted on laboratory scale, the filter fixed bed method was used and the adsorbent (activated charcoal) is a granular of 500μm mesh size. The pH, viscosity and transmittance of each solution were measured...

Aminocyclopyrachlor is a pyrimidine carboxylic acid herbicide used to control broadleaf weeds and brush. Amending soil with activated charcoal is recommended to prevent off-site transport of aminocyclopyrachlor and non-target plant damage. We used the batch-equilibrium method to determine the concentration of aminocyclopyrachlor in a pseudo-steady state with biochar, soil, and biochar-soil syst...

In this study, a new drug product containing activated charcoal was designed and developed. The excipient levels in the pharmaceutical formulation were optimized using a mixture design approach. The adsorption power of the activated charcoal suspension was selected as the critical quality attribute influencing the efficacy of medical treatment. Significant prognostic models (p<0.05) were obtain...

Techniques are described for the coating of sorbents to be used in an artificial liver support system based on mixed sorbent bed hemoperfusion. Activated charcoal has been coated with cellulose acetate (CA) by solvent evaporation. With Amberlite XAD-4, the Wurster technique was used for coating with CA. XAD-4 has also been coated with a synthetic polyelectrolyte with anticoagulant activity by a...

heavy metals in water resource are one of the most important environmental problems of countries. chromium is considered as one of the important environmental pollutants due to its toxicity considered as water contaminant that may disturb metabolic activity. this research aims to study the potential of jujube fruit powder for low cost adsorption of cr (vi) in compression with granular activated...

Cyperus scariosus R.Br is a valuable multipurpose medicinal herb, which belongs to family Cyperaceae. It possesses astringent, anti-inflammatory, diaphoretic, diuretic, cordial and stomach ache properties. An attempt has been made to study in vitro regeneration, floral bud induction, multiple shooting and multiple rooting has been achieved via healthy, moderate axillary buds as explants. The ax...

Bile-tolerant Helicobacter spp. are emerging human and animal pathogens. However, due to their fastidious nature, which requires nutrient-rich complex media to grow, infection with these bacteria may be underestimated. The accumulation of toxic metabolites in cultures may be one of the main obstacles for successful culture of these organisms. The present study examined various potential growth-...

The conductance of a piece of activated carbon immersed in water has been measured at several different temperatures. The upward and downward flow Qf water as well as the flow in the horizontal direction in the same piece was made possible by using various arrangements of the apparatus. The rate of increase in the conductance has been interpreted as the rate offlow of water into the pores ofact...

An important factor affecting the micropropagation is the quality and rate of shoot multiplication. The objectives of this work are to study the effect of concentration and BA continuous presence, and the addition of activated charcoal during two periods of culture on Berberis buxifolia morphogenesis processes during in vitro shoot multiplication. The addition of BA in the three subcultures fav...
