1. The method was applied to analyze phthalic acid esters of environmental hormone in wastewater. Four kinds of phthalic acid esters (DEP, BBP, DBP and DEHP) were checked out.

2. Phthalic acid ester is a kind of plastication material, as time goes on, it will transfer from plastics to external environment, and now it becomes a widespread global environmental pollutant.

3. Phthalic acid esters (PAEs) are a class of refractory poisonous deleterious organic compounds.

4. In the studied phthalic acid esters compounds, the occupied proportions of di(2-Ethylhexyl) phthalate(DEHP) and din-butyl phthalate(DBP) were higher relatively.

5. Allelopathy of phthalic acid and propanedioic acid of root exudations of soybean on pathogenic fungi producing by root rot was studied by indoors culture experiments and statistical method.

6. Therefore, the intermediate product is phthalic acid and final products are phthalic anhydride, carbon dioxide and water.

7. The total concentrations of terephthalic acid and phthalic acid were higher in summer and winter, but lower in spring and autumn.sentence dictionary

8. With the pure bastnasite mineral as the research object, the flotation effect of applying the mixtures of phthalic acid, hydroxamic acid, isooctyl alcho holand kerosene were studied.

9. A nitrofluorescein compound was obtained from 4 - nitro phthalic acid and resorcinol a yield of 85.

10. Thermosetting resin, obtained as reaction product from glycerol and phthalic acid.

11. Alkyd resin: Thermosetting resin, obtained as reaction product from glycerol and phthalic acid.

12. Results 22 compounds were identified and was 99% of the total peak area, in which, the Phthalic acid mono-(2-ethylhexyl) ester was 87%.

13. In this paper, the development of the analysis methods of phthalic acid esters has been introduced in details.

14. Compared with the single electrochemical oxidation, the removal rate to phenol, phthalic acid and phenylformic acid within the same time is improved by 79 to 96 percent.
