Foreword

This standard is one nitrate fertilizer, P and K series of standard test methods for nitrate, which are listed below national standards. --- GB/T 10511 "After distillation of total nitrogen content for nitrophosphate titration method"; --- GB/T 10512 "nitrate fertilizer phosphorus content - Quinoline phosphomolybdate gravimetric method"; --- GB/T 10513 "nitrophosphate determination of water content Karl Fischer method"; --- GB/T 10514 "nitrophosphate determination of water content - Oven method"; --- GB/T 10515 "Nitrophosphates particle size determination"; --- GB/T 10516 "nitrate fertilizer particles have an average crush strength of determination." This standard replaces GB/T 10512-1989 "nitrate fertilizer phosphorus content - Quinoline phosphomolybdate gravimetric method." This standard and GB/T 10512-1989 main differences are. --- Reagent solution, such as a standard titration solution preparation and calibration methods are the implementation of HG/T 2843 standards; --- The phosphorus extractants neutral ammonium citrate into 37.5g/disodium edetate solution of L; --- A chapter in the reagents and materials increased content security warning. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee under the jurisdiction of fertilizer and soil conditioner and is responsible for interpretation. This standard was drafted. Tianji Coal Chemical Industry Group Co., Ltd., National Fertilizer Quality Supervision and Inspection Center (Shanghai). The main drafters. Zhang Jiahong, Wang Yin, Li Yongping, Guo Lian Hong, Yang. This standard was first published in 1989. Determination of phosphorus content for nitrophosphate Quinoline phosphomolybdate gravimetric method

1 Scope
