摘      要：Portable measurement of ammonia nitrogen in water is of great significance for water qual-ity ***’s beneficial to reduce biological diseases and promote aquatic product *** methods such as Nessler’s reagent method suffer from complex opera-tion,time delays and toxic *** realize simple and pollution-free detection,this paper develops a low-cost portable device for ammonia nitrogen detection.A test paper was proposed to cooperate the device and offer a chromogenic *** portable device reduces the impact of any ambient light,simplifies the operation,and provides human–computer *** result obtained for the detection range of 0.4–10 mg/L(R^(2) are 0.9902 and 0.9893 for the rang of 0.4–4.5 and 4.5–10 mg/L,respectively)with the detection limit of 0.36 mg/L,and the average recovery of aquaculture water is 100.98–137.75%.The results show that the portable device can provide a great potential for on-site detection ammonia nitrogen concentration.
