摘要: Abstract Presented here is the influence of membrane pore size and dissolved organic matters on diffusion coefficient ( D ) aqueous arsenate, investigated by cell method for first time. The pH-dependent arsenate was determined compared with values from previous studies; found to decrease increasing pH, showing validity our novel method. value increased dramatically as a function at small sizes, then slowly sizes larger than 2.0 μm. Using ExpAssoc model, maximum be 11.2565 × 10 − 6 cm 2 /sec. presence led dramatic increase which could attributed electrostatic effects ionic salts. These results improve understanding behavior especially important role various environmental parameters in study prediction migration aquatic water systems.
