The large quantity of agricultural waste materials that poses disposal challenge to our environment could be converted into useful products such as activated carbon (AC).
Converting such agricultural waste to useful materials such as adsorbents could solve their disposal problems.
Commercially, the precursor materials used commonly for AC production is coal but due to its high cost, high demand and non-renewable nature made researchers to look for alternatives.

It is convienent to use the heat-enthalpy which defined by the enthalpy of the materials changed with the temperature.
That is: ( )pH C T dTρ= ∫ (1) here, H is the enthalpy of the materials, ρ is the density of the materials, Cp is the special heat of the materials which is the function of the temperature, T.

Introduction With the development of science and technology, the rapid rise of industry and the dramatic increase in human activities, especially the wastewater containing chromium emissions produced in the mining, processing, smelting, electroplating, chemical, leather and electronics industries and the emergencies arise of serious environmental pollution , it not only causes pollution of surface water, but also is worsening the contamination of groundwater, even posed a threat on human health and the environment[1,2].
Considering the higher reducibility of iron filing, the availability of raw materials and some characteristics of wastes reuse and “making them profitable”, at the same time, there are less researches of regression analysis on the restoration effect to the groundwater contamination both at home and abroad, this paper tried to study the treatment effect of iron filing, as PRB filling medium, on restoring groundwater with chromium contamination and made regression analysis about it.
