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.
A given amount of catalysts and 50 mL of methyl orange
solution were placed in a 100 mL glass beaker thermostated using a water jacket.

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.
, 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 .
