At zero field, CePt_3P exhibits a moderately enhanced Sommerfeld coefficient of electronic specific heat γCe=86 mJ/mol·K^2 as well as two successive magnetic transitions of Ce 4f moments: an antiferromagnetic ordering at T_(N_1) = 3.0 K and a spin reorientation at T_(N_2)=1.9 K. The value of T_(N_1) shifts to lower temperature as magnetic field increases, and it is ultimately suppressed around B_c ～3.0 T at 1.5 K. No evidence of non-Fermi liquid behavior is observed around B_c down to the lowest temperature measured. Moreover, γ decreases monotonously with increasing the magnetic field. On the other hand, the electrical resistivity shows an anomalous temperature dependence ρ∝T^n with the exponent n decreasing monotonously from ～2.6 around B_c down to ～1.7 for B = 9.0 T. The T-B phase diagram constructed from the present experimental results of CePt_3P does not match the quantum criticality scenario of heavy fermion systems.展开更多

The adsorbent obtained from sludge contributes to sludge disposal, while reducing the fresh ferric chloride dosage. The enhanced removal efficiencies of turbidity, UV(254), COD, total phosphorus (TP) are 90.48%,77.80%,50.62% and 96.33% respectively when 3 g/L of the sludge-adsorbent was used in the coagulation process. The maximum adsorption capacity (Q°) of the sludge-adsorbent for COD was over 184.52 mg/gand that for TP was 4.98 mg/gadsorbent optimally as the dosage of the adsorbent was 0.6 g/L. When 10 mg/L of ferric chloride and 0.6 g/L of the adsorbent were used at the first stage simultaneously, the enhanced removal efficiencies of turbidity, UV(254), COD, TP were 83.33%,52.30%,48.84% and 88.96% respectively. The pH value in the raw water played a significant role in the coagulation and adsorption process. The optimum pH value was between 4 and 11.展开更多
