optimizing the conditions of cationic polyacrylamide inverse,cationic polyacrylamide (cpam) emulsifier is widely applied in the wastewater treatment industry, mining industry, paper industry, cosmetic chemistry, etc. however, optimization of input parameters in the synthesis of cpam by using the traditional approach (i.e., changing one factor while leaving th .
acute and long-term effects of anionic polyacrylamide apam
results show that none of the apam molecules caused mortality in acute exposure experiments in adult c. finmarchicus even at high exposure concentrations (≥1000 mg/l). comparing toxicity of the 2800 kda apam between c. finmarchicus and the standard marine toxicity test copepod acartia tonsa showed that the latter was slightly more sensitive

application of flocculants in wastewater treatment.abstract. flocculation is an essential phenomenon in industrial wastewater treatment. inorganic coagulants (salts of multivalent metals) are being commonly used due to its low cost and ease of use. however, their application is constrained with low flocculating efficiency and the presence of residue metal concentration in the treated water.
enhanced removal of fluoride by tea waste supported hydrous
a novel and low-cost biosorbent of tea waste supported hydrous aluminium oxide (tea–apam–al) was prepared with help of anionic polyacrylamide (apam) for highly efficient defluoridation of drinking water. batch adsorption studies were carried out by varying the adsorbent dosage, initial fluoride concentration, conta

optimizing the conditions of cationic polyacrylamide inverse
from 7 to 7.5 h, this phase mainly developed polymer chains, and the obtained cpam had the maximum mass. when we further increased the reaction time to 8 h, the polymer tended to decrease, and the cpam’s molecular weight decreased. for conversion efficiency, the effects of stirring speed, temperature, and reaction time are shown in figure 11.
