Specific statistical methods can be used when monitor the degree of water pollution in a target zone. The purpose of usage of time series properties is to understand the driving forces and structures that produce the observed data and to fit the data into a model and proceeds them to forecasting, monitoring or even feed back and feed forward control. The essential difference between modelling data via time series methods and using the process monitoring methods is that in time series analysis the data points taken...

The presence of heavy metals in environmental factors remains among the most important concerns at national and international levels, while at the same time novel biomaterials usually derived from agricultural wastes are designed and tested for their removal below admitted limits. In this respect efficiency of biosorption of Hg2+ and Pb2+ on corn cobs have been studied for different working parameters: initial solution concentrations of heavy metals, particle size of biomass and temperature. The kinetic model for ...
