Many complex systems produce outcomes having recurring, power law-like distributions over wide ranges. However, the form necessarily breaks down at extremes, whereas the Weibull distribution has been demonstrated over the full observed range. Here the Weibull distribution is derived as the asymptotic distribution of generalized first-order kinetic processes, with convergence driven by autocorre...

Backgrounds and Objectives: Determination of arsenic(As) in drinking water has received increasing interest due to its detrimental effects on health. The aim of this research is to investigate effect of coating coral limestone using aluminum sulfate as an adsorbent on the arsenic(V) removal efficiency from aqueous solution. Materials and Methods: In this laboratory scale study, we prepared cor...

Introduction and purpose: Aniline and phenol are used in a wide range of industries, namely dye material, rubber, pesticide, plastic, and paint industries. These chemicals are released to the environment via effluent. This study aimed to investigate the efficiency of modified Pistacia terebinthus in removal of phenol and aniline from aqueous solutions. Methods: In this ...

Background and Objectives: Among the heavy metals cadmium is of considerable environmental and health significance because of its increasing mobilization and human toxicity. The objectives of this research were to synthesize SDS modified magnetite nanoparticles (Fe3O4) and to determine its efficiency in cadmium removal from aqueous solutions. Materials and Methods: Modified magnetite nanoparti...

A thermally enhanced pump-and-treatment method for pentachlorophenol (PCP)-contaminated soil and groundwater has shown potential advantages over the traditional pump-and-treatment method. Studies on the desorption kinetics of PCP from aquifer soil are the first step toward quantitative assessment of the newly proposed method. Five series of desorption batch tests were conducted at different tem...

sorption reactions in many heterogeneous systems are important. adsorption is a time dependent process and knowing the adsorption rate is essential for designing, evaluating and recovering the adsorbents. at the present study, an ammonium adsorption kinetic experiment by some soils series of golestan provice, which is varying in mineralogical and textural properties was conducted using solution...
