Role of Co-Ion Specificity and Dissolved Atmospheric Gas in Colloid Interaction

摘要: Co-ions, dissolved atmospheric gas, and buffers are shown to play an apparently remarkable role in colloidal particle interactions. The effects exhibited flocculation studies on suspensions of charged solid paraffin particles. cannot be explained by present theories colloid science. In the standard theory, co-ions, electrolyte ions same charge as a particle, ought exhibit little or no qualitative variation their stability suspensions. Dissolved gas has been assumed have role, always thought influence interactions via pH alone. this work, reasons that theory is inadequate advanced.
