【摘要】 本文用分光光度法研究了硝普钠（SNP亚硝基铁氰化钠）水溶液的光分解,探讨了硝普钠水溶液浓度Ci(1.7～16.8×13^-3mol/L)和辐照光强度I₀（120～8400Lux）对其分解速率的影响,讨论了硝普钠光解的可能机理,实验表明光照强度和溶液浓度对硝普钠水溶液的稳定性都有显著影响,同时表明用分光光度法测定其光解产物是可行的方法。更多还原

【Abstract】 The photodegradation of sodium nitro prusside (SNP) in aqueous solution has been studied by spectrophotometric method, The dependence of photolytie rate on irradiation light intensity and solution concentration has been investigated. The possible photodecomposition schema of SNP aqueous solution have been discussed. Experimental results show; the stability of SNP aqueous solution is affected by the irradiation light intensity and the solution coneentration; and the spectrophotometry is effective method for determinating the photodecomposition products of SNP aqueous solution更多还原
