The biosorption performance of both batch and liquid-solid fluidized bed operations of dead fungal biomass type (Agaricusbisporus ) for removal of methylene blue from aqueous solution was investigated. In batch system, the adsorption capacity and removal efficiency of dead fungal biomass were evaluated. In fluidized bed system, the experiments were conducted to study the effects of important parameters such as particle size (701-1400�m), initial dye concentration(10-100 mg/L), bed depth (5-15 cm) and solution flow rate (5-20 ml/min) on breakthrough curves. In batch method, the experimental data was modeled using several models (Langmuir,Freundlich, Temkin and Dubinin-Radushkviechmodels) to study equilibrium isotherms, the experimental data followed Langmuir model and the results showed that the maximum adsorption capacity obtained was (28.90, 24.15, 21.23 mg/g) at mean particle size (0.786, 0.935, 1.280 mm) respectively. In Fluidized-bed method, the results show that the total ion uptake and the overall capacity will be decreased with increasing flow rate and increased with increasing initial concentrations, bed depth and decreasing particle size.

The aim of this study is to use the dry fibers of date palm as low-cost biosorbent for the removal of Cd(II), and Ni(II) ions from aqueous solution by fluidized bed column. The effects of many operating conditions such as superficial velocity, static bed height, and initial concentration on the removal efficiency of metal ions were investigated. FTIR analyses clarified that hydroxyl, amine and carboxyl groups could be very effective for bio-sorption of these heavy metal ions. SEM images showed that dry fibers of date palm have a high porosity and that metal ions can be trapped and sorbed into pores. The results show that a bed height of 6 cm, velocity of 1.1Umf and initial concentration for each heavy metal ions of 50 mg/L are most feasible and give high removal efficiency. The fluidized bed reactor was modeled using ideal plug flow and this model was solved numerically by utilizing the MATLAB software for fitting the measured breakthrough results. The breakthrough curves for metal ions gave the order of bio-sorption capacity as follow: Cd(II)]Ni(II).

Исследовано влияние обработки свежих плодовых тел шампиньонов (Agaricus bisporus) ультрафиолетовым излучением в коротковолновом диапазоне С (100–280 нм) дозами 160, 320, 480, 640, 800 Дж/м2 при плотности потока мощности 2,7 · 103Дж/с · м2 на изменение качественного показателя хранимоспособности – текстуры грибов в процессе холодильного хранения. Хранение упаковок с грибами осуществляли в холодильной камере при t 4–5°С и относительной влажности воздуха 85–90%. Контроль изменения показателя хранимоспособности проводили по истечении 1, 3, 8, 13, 16, 21, 24 и 27-ми сут. В процессе хранения исследовали динамику изменения текстуры грибов, кг/см2. Установлено, что обработка в диапазоне доз до 418 Дж/м2 приводит к негативному эффекту изменения хранимоспособности и является нецелесообразной. Определено, что обработка УФ излучением в диапазоне доз 418–800 Дж/м2 приводит к увеличению хранимоспособности и достигает своего экстремума при 685 Дж/м2. При экстраполяции результатов экспериментальных данных такая тенденция отмечается, предположительно, до дозы 876 Дж/м2. Получены динамики текстуры в процессе хранения после обработки УФ излучением. Разработано математическое описание зависимости предельной хранимоспособности по показателю текстуры грибов от дозы облучения. The effect of irradiation of fresh the fruiting bodies of champignons (Agaricus bisporus) with ultraviolet radiation in the short – wave range C (100–280 nm) doses of 160, 320, 480, 640, 800 J/m2at a power flow density of 2,7 · 103 J/s · m2 on the change in the quality indicator of ability to store – the texture of mushrooms during cold storage was studied. Packages with mushrooms were stored in a refrigerator at t 4–5°C and relative humidity 85–90%. Monitoring of changes of ability to store was carried after 1, 3, 8, 13, 16, 21, 24 and 27 days. During storage, studied the dynamics of changes in the texture of mushrooms, kg/cm2. It was found that irradiation in the dose range up to 418 J/m2 leads to a negative effect of changes of ability to store and is impractical. It was determined that ultraviolet radiation in the dose range of 418– 800 J/m2leads to an increase of ability to store and reaches extreme at 685 J/m2. When extrapolating the results of experimental data, such a tendency is presumably observed up to a dose of 876 J/m2. The dynamics of the texture obtained during storage after processing with ultraviolet radiation. A mathematical description of the dependence of the maximum storage capacity in terms of the texture of mushrooms on the radiation dose is developed.
