Precipitation chemistry is important for understanding atmospheric chemistry and transportation mechanism for a region. Therefore, 6-h rain samples were collected manually on the Black Sea Region of Turkey between March 2019 and May 2019. Totally, 21 wet deposition samples were collected in 12 rainy days. The collected rain samples were analyzed by ion chromatography for ions, including Cl⁻, NO₂⁻, NO₃⁻, SO₄²⁻, Na⁺, Ca²⁺, Mg²⁺, K⁺, NH₄⁺. Volume weighted mean (VWM) concentrations of ions were calculated and were in the order of Na⁺ > Ca²⁺ > Cl⁻ > SO₄²⁻ > NO₃⁻ > Mg²⁺ > K⁺ > NH₄⁺> NO₂⁻. The pH values of individual precipitation varied from 4.70 to 8.07. Anion to cation ratio was 0.74 ± 0.34 thus it was an indication of anion deficiency. A strong correlation between NH₄⁺ and SO₄²⁻, NH₄⁺ and NO₃⁻, Ca²⁺ and SO₄²⁻, Ca²⁺, and NO₃⁻ was found in the samples due to the neutralization process. The back trajectory model was used to find the long-range sources and the influence of air masses coming from Saharan, Europe, and the Black Sea. Calcium ion was found to be an effective ion in the neutralization processes by analysis of multiple linear regression and neutralization factor calculation. Approximately 79.5% of SO₄²⁻ and 59.7% of NO₃⁻ were neutralized by Ca²⁺ and NH₄⁺. The washout mechanism for Na⁺, Mg²⁺, Ca²⁺, and K⁺ was dominantly observed on the March 12, 2019. Rainout mechanism was seen on the April 13, 2019 rain event due to the long-range transportation from Saharan Dust.

沉淀化学对于了解一个地区的大气化学和运移机理很重要。因此，在2019年3月至2019年5月之间，在土耳其黑海地区手动收集了6小时的降雨样本。在12个雨天共收集了21个湿沉降样本。将收集的雨水样品通过离子色谱分析对离子，包括氯^-，NO ₂ ^-，NO ₃ ^-，SO ₄ ^2-，钠⁺，钙²⁺，镁²⁺，K ⁺，NH ₄ ⁺。计算离子的体积加权平均（VWM）浓度，其顺序为Na ⁺ >的Ca ²⁺  >氯^-  > SO ₄ ^2-  > NO ₃ ^-  >镁²⁺  >ķ ⁺  > NH ₄ ⁺ > NO ₂ ^-。单个沉淀物的pH值在4.70至8.07之间变化。阴离子与阳离子的比率为0.74±0.34，因此表明阴离子不足。NH之间的强相关性₄ ⁺和SO ₄ ^2-，NH ₄ ⁺和NO ₃ ^- ，钙²⁺和SO ₄ ^2-，钙²⁺，和NO ₃ ^-由于中和过程，在样品中发现了。反向轨迹模型用于查找远程源以及来自撒哈拉，欧洲和黑海的气团的影响。通过多元线性回归和中和因子计算分析，发现钙离子是中和过程中的有效离子。的SO约79.5％₄ ^2-和NO的59.7％₃ ^-是由钙中和的²⁺和NH ₄ ⁺。Na ⁺，Mg 2 ⁺，Ca ²⁺和K ⁺的清除机理 观测主要在2019年3月12日观察到。由于撒哈拉尘土的远程运输，在2019年4月13日的降雨事件中看到了降雨机制。
