Thus, it is necessary to develop efficient methods for chlorate removal from drinking water, and various treatment technologies have been developed including chemical reduction [3], biological method [4, 5] and adsorption method.
Langmuir and Freundlich adsorption isotherms models were used to analyze the equilibrium adsorption data.
The pseudo-first-order (Eq. 3) and pseudo-second-order (Eq. 4) kinetic models were used to fit the experimental data,equations in linear forms are expressed as follows [11]: (3) (4) Where and are the amount of adsorbent at time t and equilibrium, respectively; and are the pseudo-first-order and second-order rate constants for the adsorption process.

Training data for ANFIS with the volume n = 100 were obtained using these grid functions.
Increasing the number of membership functions, complicating their form, and increasing n of more than 100 points in the array did not cause any significant reduction of the approximation error.
In such a case, the data for ANFIS are formed by multiplying or dividing by 2 depending on the ratio of the Je and Ju values, which allows achieving the purpose of control even if the delay in the system increases significantly.

It involves MnO4- reduction and the deposition rate is governed by diffusion–electromigration kinetics.
The data were collected using an electrochemical workstation (Autolab/PGSTAT M101, Netherlands).
MnO2 nanoparticles shows very high specific capacitance values calculated from CV and charge-discharge data of 306 F g‒1 and 238 F g‒1 at 10 mV s-1 and 0.8 A g‒1 respectively.

The data of the experiments were subjected to one-way analysis of variance (ANOVA) using SPSS version 13.0 for Windows (SPSS Inc.).
This phenomenon was consistent with the data of DPPH radical scavenging activity.
For the reducing power assay, the presence of antioxidants could result in the reduction of the Fe3+/ferricyanide to the ferrous form.

The prediction can lead reduction in computation or experimental time and cost of the practitioners.
However, when the network begins to over fit the data, the error on the training set will typically begin to rise.
The input and response data obtained from numerical model shown in Table 1 is used for prediction purpose.

Introduction
The technique of ECAP has ability to apply high shear strain (~1) into metal rods pass by pass
without reduction of cross-section area [1].
The raw data were processed by HKL-Channel 5.
All data were obtained from EBSD.

One plausible explanation is the surface adsorption
of H species leading to the reduction in surface resistance in a fashion similar to the oxide-based
sensors [9].
The experimental data observed indicate that surface adsorption is a possible gas sensing mechanism for the observed gas sensor response of the GaN resistive sensors.
More experimental data are needed to clarify the likely gas sensing mechanisms.

The data have been fitted to the high temperature constitutive creep
equation:
Where σ is the stress, •ε the strain rate, k the Boltzmann constant, T the absolute
temperature, n the stress exponent and Q the activation energy.
Gust et al. [9] pointed out a reduction of the flow stress by a factor of 5 for YTZP doped with BaS, with grain size of 400 nm at 1300ºC.
The preliminary results on the temperature dependence or Q values obtained for YTZP nanocrystals are in good agreements with the few data reported in literature for samples with a mean grain size of 100 nm, but there is a discrepancy with the values obtained for submicron-specimens.
