methyl orange using polymer-titania microcomposites, J.
Time-dependent adsorption studies show that C1 is a good candidate for the adsorption of chlorophenols,
methyl orange, and Eriochrome Black T.
In the equation, [C.sub.0] is the initial concentration of
methyl orange solution, C is the concentration after adsorption, V is the volume of solution, m is the weight of microspheres (g), and Q is mass of adsorbed
methyl orange per gram of microsphere.
Before the beginning of photolysis,
methyl orange solution was accurately measured and add to five 50 mL quartz tubes.
After decolorization of the three mentioned dyes (malachite green, Congo red and
methyl orange) by fungal isolate, they were tested for their toxicity against both of Caco-2 and fibroblast cells compared with dyes containing water with final concentrations of 5, 10, 15, 20 and 25 mg/L.
The concentration change was calculated from the linear calibration plot of the non-hydrogenated
methyl orange at a wavelength of 465 nm.

methyl orange solution using Ag/C codoped Ti[O.sub.2] photocatalysts with different contents of Ag under visible light irradiation at 25[degrees]C and pH 7.
Meanwhile, it was found that in degradation of
methyl orange or 4-4-[(dimethylamone)phenylazo] benzenesulfonic acid, a Ti[O.sub.2] film was up to 50% less effective than the Ti[O.sub.2] slurry.
Degradation of
Methyl Orange. Eight test solutions of 20 mg/L
methyl orange were prepared by dissolving
methyl orange granules in deionized distilled water.
Benzophenone (BP), 2-hydroxyethyl methacrylate (HEMA),
methyl orange (MeOr), Zn[(N[O.sub.3]).sub.2], and oxalic acid were used as purchased from Lingfeng Shanghai Reagent Co.
Methyl orange, an anionic dye has been used as a probe to study the mode and the extent of complex formation between small molecules, proteins and water-soluble polymers [9].
