water-soluble phosphoric acid

Methods The chromatographic conditions included a column YWG C18, mobile phase: methanol-water ( 50 ∶ 50), adjusting to pH 3.0 by 0.3% triethylamine solution and phosphoric acid, flow rate 1 ml/ min, and wavelength 230 nm.

流动相为甲醇-水（50∶50，含0.3%三乙胺，磷酸调pH3.0）；流速1ml/min；

The presence of aggressive cover water containing phosphoric acid and having a pH of 1. 61-1. 83 was a factor accelerating attack.

含磷酸的密封水（pH在1.61～1.83）具有腐蚀性，加速了腐蚀进程。

They always connected water with their attitude. Production Summary of the HDH Process Phosphoric Acid Plant of Honghe Phosphate Fertilizer Factory
