SEPARATION AND RETENTION BEHAVIOUR OF BENZIMIDAZOLE DERIVATIVES IN THIN LAYER CHROMATOGRAPHY ON SILICA GEL
The separation ability and retention behaviour of normal phase TLC on silica with eight nonaqueous eluents, has been studied by measuring the retention constants of a series of synthesized benzimidazoles. The separation ability and retention behaviour are discussed in terms of the nature of the solute and eluent....

WASTE COPPER USAGE FOR PLANT FUNGICIDE PRODUCTION
Copper Oxyl Chloride 3Cu (OH)2∙CuCl2 is dual salt of copper, chlorine, oxygen and water. It is light green salt without smell. In water and organic solutions it is insoluble while it is easily solluble in acids. It is solluble in ammonia thus building complex units. It is more instable product since it is soluted after longer exposure to air a...

PREDICTION MODELS OF NON-FERROUS SECONDARY RAW MATERIALS FORMATION
For the prediction of formation of non-ferrous processing and accumulating waste both model of balancing and model of correlation and regression analysis can be employed, while the dynamic model can be applied only for the accumulating waste. Estimates of the formation of certain type of metallic secondary raw materials in model of balancing are ba...

A THERMODYNAMIC ASPECTS OF METALLIC SECONDARY RAW MATERIALS RECYCLING POSSIBILITY
Industrial products are made from different materials, therefore existing metallurgical plants are not always able to adequately process them. Knowing the thermodynamic parameters, possibility and degree of removal of contamininats from the base metal in the recycling process can be predicted. Such approach facilitates a decisions about products de...

MEMBRANE PROCEDURES IN COMMUNAL WASTE LANDFILL LEACHATE TREATMENT
One of basic problems faced in practice of landfill waste treatment is a problem with landfill leachate. The intensity of their production, thus their quantity, depends on numerous factors: landfill age, waste types, microclimatic parameters and similar. This leachate must not be discharge directly into the environment without their previous collec...
