It was reported that modified rice husk is a potentially useful material for the removal of Copper and Lead from aqueous solutions.
The maximum adsorption capacity of modified rice husk is 292.5 mg/g-adsorbent.
Licenses for nearly 70 patents had to be cleared out before the genetically modified rice could be marketed (van den Belt [2003]; Wilson [2007]).
The formulation with 5 g 100 g−1 refined sugar (sucrose), 40 g 100 g−1 milk powder and 55 g 100 g−1 modified rice flour was selected, considering the highest values for solubility in water (49.8 g 100 g−1) and in milk (46.4 g 100 g−1), the luminosity (88.8) of the dry mix, and the firmness (0.19 N) of the prepared formulation.
After this treatment, the modified rice husk was filtered and washed with distilled water for several times until the pH reached a constant value.
The thermodynamics analysis results indicated that the adsorption of RB4 onto the modified rice bran adsorbent is an endothermic, spontaneous monolayer adsorption that occurs through a physical process.
The potential application of chemically modified rice straw (RSGM) was investigated in a fixed-bed adsorber as an extension of our previous batch adsorption studies.
The effects of independent variables such as dye concentration (100 500 ppm), adsorbent dosage (20 120 mg) and temperature (30 60 °C) on the dye adsorption capacity of the modified rice bran adsorbent were investigated by using the response surface methodology (RS M.
The use of gums in pasta formulated with thermo-mechanical modified rice flour could be significantly reduced by substituting them partially with gelatinized corn starch, without reduction of noodle quality.
The results showed that the dye maximum adsorption capacity of the modified rice bran adsorbent was 151.3 mg g−1 with respect to a dye concentration of 500 ppm, adsorbent dosage of 65.36 mg, and temperature of 60 °C.
