Improvement of cadmium ion removal by base treatment of juniper fiber.
TL;DR: BTJF could be an inexpensive and efficient sorbent for removing heavy metals from stormwater runoff because of its strong ability to bind cadmium and its faster kinetics in low concentration.

Adsorption characteristics of Cu and Zn onto various size fractions of aggregates from red paddy soil.
TL;DR: Pseudo-second order model was more successful to fit the adsorption process in the kinetic experiments and the isothermal experiments data can be described well with the Freundlich model as a whole.

Yanhui Li,Qiuju Du,Tonghao Liu,Jiankun Sun,Yuqin Jiao,Yanzhi Xia,Linhua Xia,Zonghua Wang,Wei Zhang,Kunlin Wang,Hongwei Zhu,Dehai Wu +11 more
TL;DR: In this paper, the effect of pH, dosage, contact time, and temperature on the adsorption properties of phenol onto graphene were investigated, and the results showed that the maximum adsorbing capacity can reach 28.26 µm/g at the conditions of initial phenol concentration of 50 mg/L, pH 6.3 and 285 K.

Modeling of sorption kinetics: the pseudo-second order equation and the sorbate intraparticle diffusivity
TL;DR: The applicability of the pseudo-second order equation (PSOE) has been explained on the ground of the model assuming that the overall sorption rate is limited by the rate of sorbate diffusion in the pores of sorbent (intraparticle diffusion model).

Effect of pH on cadmium biosorption by coconut copra meal.
Augustine E. Ofomaja,Yuh-Shan Ho +1 more
TL;DR: Cadmium biosorption by copra meal was found to be dependent on the initial solution pH and initial cadmium concentration, and mathematical relationships were drawn to relate the change in the solution hydrogen ion concentration with equilibrium biosor adaptation capacity.
