聚丙烯酰胺（Polyacrylamide）的理化指标应符合表1的要求。
干燥减量的测定：称取约1g试样，精确至0.0002g，置于已恒重的称量瓶中，在120℃±2℃的干燥箱中干燥至恒重。
丙烯酰胺单体含量的测定：采用高效液相色谱法，以C18反相色谱柱分离，在205nm波长处检测。
砷（As）的限量：≤3 mg/kg，按GB/T 5009.11或GB/T 5009.76规定的方法测定。
This standard applies to polyacrylamide as a food additive, produced by polymerization using acrylamide as raw material.
The physicochemical indicators of polyacrylamide shall comply with the requirements in Table 1.
Determination of loss on drying: Weigh about 1 g of the sample, accurate to 0.0002 g, place in a pre-weighed weighing bottle, and dry in an oven at 120°C ± 2°C to constant weight.
Determination of acrylamide monomer content: Use high-performance liquid chromatography with a C18 reversed-phase column, detection at 205 nm.
Limit for arsenic (As): ≤ 3 mg/kg, determined according to GB/T 5009.11 or GB/T 5009.76.
