Testing the Performance of Various Polymeric Antiscalants for Mitigation of Sb-Rich Precipitates Mimicking Stibnite-Based Geothermal Deposits

Table 3

The effect of Gelatin at various dosages. The concentration of the ions is given in terms of ppm. The amount of polymeric antiscalant remains in the deposit is determined by gravimetry.

Dosage/ppm	[Na^+]	[S^=]	[Sb^n+]	The amount of deposit/mg	The amount of deposit after subtracting of the polymer/mg	The amount of polymer remaining in the deposit/mg
