Removal of Fe from Aqueous Solution by Natural Apatite

The feasibility of natural apatite for adsorptive removal of Fe from aqueous solution was investigated. Batch experiments were performed as function of process parameters such as contact time, initial concentration of Fe, temperature, apatite dosage and pH. The natural apatite exhibited a high performance for the removal of Fe from aqueous solution. The pH value clearly affects the removal mech...

Assessment of spatial variability of cation exchange capacity with kriging and cokriging

Cation exchange capacity (CEC) is one of the most important soil attributes which control some basic properties of soil such as acidity, water and nutrient retaining capacity. However, the measurement of cation exchange capacity in large areas is time consuming and requires high expenses. One way to save time and expenses is to use simple soil covariates and geostatistical methods in mapping CE...
