The possible reason is that the reduction of pH value contributes to protonation of three kinds of CTS/REC-ETA, simultaneously forming more NH3+, which makes easier for them to combine with negatively charged methylene blue so as to the improvement of adsorbent capacity [20].
In order to investigate the mechanism of adsorption, two simplified kinetic models including pseudo-first-order and pseudo-second-order equations are usually used.In this paper, the pseudo-second order model is used to study the experimental data obtained.
Figure 9. shows that the adsorption behavior of three kinds of CTS/REC-ETA for MB which are fitted by Freundlich isotherm model shows better fit to the experimental isotherm data than the Langmuir isotherm model.

The lattice parameters a and c were calculated from the XRD data.
(2) where c is the lattice parameter of the sample calculated from XRD data and c0 is the lattice parameter of ZnO without strain.
By increasing the ZnO film thickness, the number of nucleation sites increases on the substrate, this let a reduction of pore density and a densification of ZnO films (fig. 5b, 5c, and 5d).

The aforementioned reduction of the magnetic interactions due to Co doping is triggered by a Mn content exceeding yMn=30.
In order to provide a consistent outline we considered the mean values of the DV/V data in a restricted range of the transformation, i.e. by taking into consideration the diffraction patterns which returned a refined phase fraction in the range ≈15-85%.
The overall consequence of this complex situation, together with the isotropic thermal expansion of austenite occurring at a different slope, gives rise to a certain degree of scattering of the DV/V data with temperature (Fig. 8); nevertheless, a mean DV/V value (being for this sample slightly higher than ≈0.9%) can still be reliably estimated.

This study was with a view to enriching the studies on carbon cycle in the Sanjiang Plain; and providing data for accurate estimates and projections of SOC pool under severe land use change in Sanjiang Plain; and providing scientific basis to identify the long-term effects of reclamation on SOC pool, and to adjust the land use structure in the balance between carbon sequestration and emission reduction and guarantying food production.
Data of meadow marsh soil were from reference[12].

The force signals are processed using the charge amplifiers and recorded by a PC-based data acquisition system.
In this work is placed on the possibility of the increase in the cutting force could be caused by tool wear, while the decrease result could be explained by the reduction in depth of cut, due to severe tool wear [26].
The mean values of Ft and Fa presented were calculated based on the data of Fig. 5 and Fig. 6, taking into account the difference between the highest peak and lowest peak.

It should be mentioned that the present data on the strength of basalt fibers in the concrete alkaline environment are quite controversial.
According to some of them, its strength in cement concretes is relatively constant during the material useful life, according to other data - fibers may destroy within 3 years [11].
Basalt fibers provide microreinforcement and the absence of shrinking deformations, increases the resistance towards crack formation in a composite material as well as facilitates hydration at the initial setting stage (decrease of internal loads) and the reduction of the setting period.

This is further corroborated by calculation data, which demonstrate that the C2 atom has the greatest magnetic moment in this pyridinic system.

As a first approach, we used the model parameters listed in Table I, as these have been well­proven in predictive simulations of Si PiN diodes and conformed well with measured data [1].
In addition, the physical models describing the temperature­dependence of heat capacity and thermal conductivity have been adjusted to fit the experimental data up to 3000K [7], close to the melting point.
The increase of the hole density cannot compensate the reduction of hole mobility, which degrades from around 16cm2/(V · s) to 10cm2/(V · s).

The significant contribution of the sliding parameter to the reduction in wear of polymer composites has rarely been reported.
Schematic two-dimensional drawing of pultrusion processing. 2.3 Taguchi Design of Experiments and Optimization Design of experiment (DOE) is a controlled and systematic method for the collection and analysis of large amounts of data in order to obtain a comprehensive assessment of the factors under investigation.
All the wear and friction data were obtained from the average of three replicates for each sample. 3.0 Result and discussion 3.1 Taguchi analysis for wear rate and average COF Experiment results and calculated S/N ratio of wear rate and average COF of kenaf fiber/polyester composites are shown in Table 3.

Recycling of natural fibres (NF) by incorporating them into composites to manufacture renewable and biodegradable materials has drawn considerable attention as a biodegradable reinforcing material [6,7] and can help in waste reduction and reduce the cost of the composites developed [8].
These data indicated that all DPF modified composite samples showed significant resistance against both brown and white rot fungi used in this trial when compared to the control solid wood samples (Pinus sylvestris) Figures 3 and 4.
The obtained data revealed an increasing in the mass loss percentages by the addition of DPF.
