ABSTRACTA specially designed titania photocatalyst was prepared by coating Ahlstrom non-woven paper, used as a flexible photocatalytic support, with Millennium PC500 anatase. At the same time, a new solar photoreactor (STEP) was designed based on the multi-step cascade falling-film principle to ensure good exposure to sunlight and good oxygenation of the effluent to be treated. Several types of reactants were treated: 4-chlorophenol as a model organic pollutant; formetanate, a widely used pesticide in horticulture; a mixture of pesticides used in vineyards; and Indigo Carmine and Congo Red, which are complex multifunctional dye molecules. Each reaction was performed simultaneously in a solar CPC slurry photoreactor and in the STEP photoreactor under identical solar exposure to better evaluate and validate the results obtained. The STEP solar reactor was found to be as efficient as the CPC one for 4-chlorophenol and formetanate total degradation. Keywords.-Pesticide, Degradation, Photocatalyst. RESUMENUn diseño especial de un fotocalizador de TiO2 fue depositado sobre un papel foto inerte. Al mismo tiempo un nuevo fotoreactor solar (STEP) fue diseñado en base a una cascada multipaso, generando buenos resultados a la exposición de la luz solar con buena oxigenación del efluente que se trato. Se utilizaron como reactivos a tratar: 4- clorofenol como un contaminante orgánico, formetano ampliamente usado como pesticida en horticultura, y una mezcla de pesticidas usadas en viñedos; así mismo el índigo carmín y congo red como complejos multifuncional de colorantes. Cada reacción fue realizada en un reactor STEP con agitación y exposición solar CPC simultáneamente para tener una mejor evaluación de los resultados obtenidos. El reactor solar STEP fue muy eficiente como el CPC, para el 4-clorofenol y formetano se obtuvo una degradación total. Palabras clave.- Plaguicidas, Degradación, Fotocatalizador.

Cationic Hydrogels

This study examined the removal of acidic indigo carmine dyes from aqueous solutions using cationic hydrogels. Irradiated hydrogels were investigated as a new sorbent for dye removal from aqueous solution. Poly(N,N-Diethylamino ethyl methacrylate) [poly(DEAEMA)] hydrogels were prepared by radiation polymerisation of N,N-diethylamino ethyl methacrylate [DEAEMA] monomer in the presence of cross-linking agent, ethylene glycol dimethacrylate [EGDMA], and used for the removal of acidic indigo carmine textile dye. The adsorption of dyes was examined using a batch sorption technique. The effects of pH, time and initial dye concentration on the adsorption capacity of hydrogels were investigated. Maximum gelation ratio was 98.2% at irradiation dose of 5.3 kGy. Maximum equilibrium volume swelling, V/V0, value was 21.3 at pH 2.8. Maximum amount of adsorbed indigo carmine onto hydrogels was 96.7 mg dye/g gel at pH 2.8, 21 h of adsorption time and 120 mg/L initial dye solution. Swelling and adsorption capacity increased with decreasing of pH. Compared with Congo red, amounts of adsorbed indigo carmine are much higher than those of Congo red. Langmuir isotherm model was the best fit for these poly(DEAEMA) hydrogels-indigo carmine systems.

Percentage Removal

SummaryA study of the removal of I131-labeled Congo red from the blood of amyloid, non-amyloid, multiple myeloma, rheumatoid arthritis and other patients is presented. The percentage removal of the labeled dye shows the same variation reported by many other workers using Bennhold’s test and its modifications.However, there seems to be a positive correlation between the percentage removal of the labeled dye and the presence of amyloid as revealed by biopsy and autopsy. The half-time of disappearance is also correlated with the amyloidosis.The availability of the I131-labeled dye permits the use of very small weights of the dye thereby drastically reducing the possibility of toxic and sometimes fatal reactions encountered with the unlabeled dye. The I131 present permits easy quantitation of the dye in the blood without separation of plasma and obviates the need of fasting. It also permits external counting and scanning of deposits in the organs containing the dye.The availability and use of the labeled dye may stimulate more comparative studies of the removal of the dye from the blood correlated with biopsy and autopsy findings.

Indirect Mechanism

SummaryIn rabbits and cats Congo red administered intravenously causes severe thrombocytopenia and ultrastructural alterations of platelets and leucocytes, similar to those produced by some fatty acids and endotoxin. Transient leucopenia is followed by leucocytosis. In contrast, incubation of Congo red in citrated blood or platelet rich plasma has no effect. Therefore, an indirect mechanism is postulated to explain the in vivo effect of Congo red.
