The parameters studied include pH, adsorbent dosage, contact time, and initial concentrations.
The factors investigated include; pH, adsorbent dosage, initial concentration, contact time and shaker speed.
The variables such as adsorbent dosage, pH, desorption time, and eluent volume was optimized.
Co II) concentration, pH of Co II) solution and adsorbent dosage.
Solution pH, contact time, adsorbent dosage and ionic strength were four studied variables on cadmium adsorption.
Three independent variables namely initial pH, dye ion concentration and adsorbent dosage were investigated.
The effects of pH, initial concentration and adsorbent dosage were investigated using response surface methodology.
Parameters optimized include: Contact time, adsorbent dosage, arsenic concentration and supernatant pH.
Four independent variables namely initial pH, metal ion concentration, temperature and adsorbent dosage were investigated.
Boron removal increased with increasing pH and adsorbent dosage, but decreased with increasing temperature.
Experimental parameters such as effect of pH, temperature, contact time, adsorbent dosage and shaking speed were optimized.
