  the sulfate radical
The sulfate radical seldom enters into particles but reacts with PVA, forming the PVA radical that yields the grafting of St onto PVA.
      
Hydrogen abstraction from PVA with the sulfate radical is the fastest reaction, which results in the grafting onto PVA, while the initiation reaction, which results mainly in homo-polymer, is slower.
      
The time of the entry of the sulfate radical into a particle was 10-4?s.
      
Ascorbate reacts with peroxodisulfate to initiate production of the sulfate radical ion (SO?-4), which reacts with formate to produce carbon dioxide radical ion (CO?-2) and sulfate.
      
Nonempirical quantum-chemical calculations of the transition states of reactions between the sulfate radical anion and organic compounds of various classes were performed, and the activation energies of the corresponding reactions were calculated.

In order to determine the sulfate radical in tannary waste waters, which contains 30% ethanol and itspHvalue equals 3.5. Barium chloride as titrant and barium ionselective electrode based on tetraglycolic bis[di(P-octyphenyl)amide] as an indicating electrode were investigated. The interference of Ca~(2+) can he eliminatedby the solution of EDTA. This method is rapid, with coefficients of variation(u=8)<1%.

在含30%乙醇、pH=3.5的溶液中,用四甘酰双[二(对辛基苯)胺]钡离子选择电极作指示电极,氯化钡为滴定剂,直接滴定皮革厂废水中硫酸根,Ca~(2+)的干扰可用EDTA溶液消除,方法快速,变异系数(u=8)<1%。
