چکیده
The adsorption efficiency of gelatin-cellulose nanocrystals hydrogel membrane (GCHM) for the removal Cu(II) and Co(II) from aqueous solution was studied in batch experiments. interactive effect independent variables such as pH, contact time, temperature, ratio gelatin cellulose on were investigated. Analysis variance (ANOVA) showed that response surface quadratic model is highly impressive can successfully predict experimental results. optimization results process by methodology- central composition design (RSM-CCD) obtained at pH 6, temperature 52.50 ℃, time 67.50 min. ration gelatin-CNCs 3:1. maximum percentage 86.95% 89.77% Co(II), respectively.

Bentazon removal from aqueous solution by reverse osmosis; optimization of effective parameters using response surface methodology
Although bentazon is widely used as an agricultural herbicide, it is harmful to humans and poses many environmental threats. This study focused on the treatment of wastewater contaminated with bentazon pesticides using membrane technology. In this regard, low-pressure reverse osmosis (RO) was employed as it has already been used in the removal of other micro-pollutants. The effects of process v...

In this study, experiments were performed based on Response Surface Methodology (RSM). The...
متن کاملModeling and Optimization of Arsenic (III) Removal from Aqueous Solutions by GFO Using Response Surface Methodology
Arsenic is a highly toxic element for human beings, which is generally found in groundwater. Dissolved Arsenic in water can be seen as As+3 and As+5 states. The adsorption process is one of the available methods to remove Arsenic from aqueous solutions. Thus, this papers aims at removing Arsenic (III) from aqueous solutions through adsorption on iron oxide granules. The relation among four inde...
