AbstractAbstract
[en] This invention concerns a process for separating free fractions from tied fractions in an immunity determination process of a type where a solution is brought into contact with a compound comprising a polysaccharide matrix or derivatives coupled or linked covalently to an antibody by a bi-functional binding agent. The polysaccharide matrix can be any matrix to which are attached a certain number of hydroxyl groups, as well as its derivatives. The preferred polysaccharide matrices include the cellulose polymers, dextran polymers, agarose and its by-products. Cellulose polymers and their derivatives are the preferred polysaccharide matrices

AbstractAbstract
[en] The regularities of the formation of carbon adsorbent from charcoal coke under the influences of ionizing radiation and heat have been studied. In both stages of obtaining active adsorbent, i.e. in coking and activation processes, the stimulating effect of radiation is observed. Thus, a temperature decline by 200-450 degrees Celsius compared with thermal processes, and an increase in sorption capacity and mechanical strength of the obtained product were observed. The sorption capacity of the activated carbon by radiation-thermal methods 2,3 times more the adsorbent produced by thermal methods. As a result of polycondensation processes occurring under the effect of radiation on the carbon material, the mechanical strength of the product increases by 11.3%. The mechanism of the investigated processes is discussed, and it is shown that the occurring processes are due to the high penetrating ability and chemical effects of ionizing radiation. The technico-economical evaluation has been conducted and it has been found that using the electron accelerator having the beam power of 5,0 kW, allows producing 28,800 tons' highquality carbon adsorbents per year.

AbstractAbstract
[en] The use of low-cost and eco friendly adsorbent was investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. Rice husk was used as an adsorbent for the removal of Murexide from aqueous solutions. The rate of adsorption was investigated under various parameters such as size of adsorbent, contact time of solution with adsorbent, temperature, pH, adsorbent dose and stirring speed for the removal of this dye. Langmuir isotherm was also applied to evaluate maximum adsorption capacity of rice husk for Murexide. On the basis of results obtained, it is proposed that rice husk can be effectively used for the elimination of Murexide from waste water. (author)

AbstractAbstract
[en] Process for decontaminating a radioactive effluent containing ruthenium at least. Under this process, in an effluent containing radioactive elements, a certain number of precipitates are formed which exhibit absorbent and/or co-precipitant properties with respect to the radioactive elements contained in the effluent, the precipitates being formed without intermediate phase separation. It is characterised in that a cobalt sulphide precipitate is formed in the effluent to be processed

AbstractAbstract
[en] Rice husk and saw dust are attempted as alternate adsorbents to charcoal for the removal of reactive dye, namely remazol brilliant blue from aqueous media. The adsorption of remazol brilliant blue has been studied onto rice husk, saw dust and charcoal at different shaking times, adsorbent dosage, temperatures and pH values and their results are compared. The adsorption data was fitted to Freundlich and Langmuir isotherms and corresponding adsorption parameters for each were calculated. Pseudo first and second order kinetic models were used to calculate the amount adsorbed at equilibrium (qe). The calculated values of qe for pseudo-second order equation were found to be in good agreement with those of experimental values. The monolayer capacity (Vm) for rice husk (0.699 mg g/sup -1/) is greater than that for charcoal (0.074 mg g/sup -1/) and saw dust (0.114 mg g/sup -1/). It is concluded that rice husk is found better adsorbent for the removal of remazol brilliant blue as compared to charcoal and saw dust. (author)
