Research summary
تناول البحث دراسة تثبيط تآكل الحديد في وسط حمضي باستخدام الفانيلين كمثبط. تم استخدام طريقة الانخفاض في الوزن لتحديد معدل التآكل في محلول حمض الهيدروكلوريك بتركيز 1M عند درجات حرارة مختلفة (20-60 درجة مئوية) وتركيزات مختلفة من الفانيلين (100-500 جزء في المليون) لمدة ساعتين. أظهرت النتائج أن كفاءة التثبيط تزداد بزيادة تركيز الفانيلين ودرجة الحرارة، حيث بلغت الكفاءة العظمى حوالي 87% عند درجة حرارة 60 درجة مئوية وتركيز 500 جزء في المليون. تم حساب المعايير التنشيطية لعملية التآكل مثل طاقة التنشيط، تغير الأنتالبية، وتغير الأنتروبية، وأظهرت النتائج أن امتزاز الفانيلين يتبع قانون لانغميور. خلصت الدراسة إلى أن الفانيلين يمكن استخدامه كمثبط فعال لتآكل الحديد في الأوساط الحمضية، وأنه يمتاز بكونه مادة صديقة للبيئة وغير سامة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال حماية المعادن من التآكل، حيث تقدم حلاً بيئيًا واقتصاديًا باستخدام الفانيلين كمثبط لتآكل الحديد. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، لم يتم التطرق إلى تأثير الفانيلين على أنواع أخرى من المعادن، مما يحد من تطبيق النتائج على الحديد فقط. ثانيًا، لم يتم دراسة تأثير الفانيلين على المدى الطويل، حيث أن التآكل عملية مستمرة وقد تتغير كفاءة التثبيط بمرور الوقت. ثالثًا، كان من الممكن تحسين الدراسة بإجراء تجارب في ظروف بيئية مختلفة مثل وجود شوائب أو ملوثات في الوسط الحمضي. وأخيرًا، يمكن أن تكون الدراسة أكثر شمولية إذا تم مقارنة الفانيلين بمثبطات أخرى مستخدمة في الصناعة لتحديد مدى تفوقه أو نقصه.

The corrosion inhibition of transmision steel in 1M HCl solution in
the presence of Succinic acid at temperature (20,30,40,50,60)°C at
concentration between (10-6- 10-4) M for two hours were studied
using weight loss method.
The aim of this work is to study the effect of the aging heat treatment on the pitting corrosion resistance of martensitic stainless steel. In this research a number of specimens from martensitic stainless steel were subjected to solution treatment a
t 1050 for one hour followed by water quenching then aging in the temperatures range (400-750) for different holding times (1-16 hrs).
After heat treatment, two types of corrosion tests (accelerated test and immersion test) were conducted. The results obtained in this research showed that the pitting corrosion resistance was
affected by Aging temperature and three critical temperatures were found in corrosion test: the
specimens aged at 475 0C had maximum corrosion rate. This may be due to the presence of stringer δ-
ferrite and precipitation of very fine precipitates which precipitated heterogeneously in the martensitic
matrix, which led to an increase in corrosion rate. The specimens aged at temperatures range (550 – 625) 0C had minimum values of corrosion rate, this is attributed to the high volume fraction of retained austenite. The specimens aged at temperatures above 625 had intermediate corrosion rate.
The type of pits, which resulted from two pitting corrosion tests, was independent form the form of δ-ferrite and carbides which presence in microstructure.
This study includes the evaluation of the problem of seawater intrusion in Al-Bassa area in
2014 through chemical monitoring of a group of sampling wells, under certain condition
that were subjected to the area during the research, representing by
rainfall precipitation in
the study area was only 500 mm/ year, as a result in the suspension of irrigation from 16
October lake and reuse of many abandoned pumping wells.
This study founds an increasing in the salinity values in the Al- Bassa coastal area of
summer in 2014, ranging between(665.6-6432mg/l)after increasing daily pumping rates, in
addition to the increasing of chloride and sodium concentrations in most of sampling wells
water in conjunction with high salinity levels. In the fall, the salinity values ranged
between 490-950 mg / l. The geochemistry of Na/Cl indicates values less than 0.84 in
most water samples during the summer, while in autumn this percentage was higher than
0.84 in most samples ,to be an indicator for marine water.
Marfona cultivar were chemical mutagen using 20, 30 and 40 mM of Ethyl Methane
Sulphonate (EMS) for 2, 3, 4 hrs in 2013. was conducted to improve potato (Solanum
tuberosum L.) tolerance to salinity. Plants Marfona mutagen from M5 and unmutagen were
cultured with Spunta and Falouka Cvs in 2015. Plants were later subjected to another
selection pressure, by irrigating them using water containing Nacl between 0-200 mM The
results showed that the gradual increase in Nacl concentrations caused a significant gradual
decreases in most vegetative, yield and its component characteristics. Mutant plants varied
with unmutant for Marfona, Spunta and Falouka in plant height varied from 68 to 41 cm
and number leaves varied from 21 to 12 leaf. and stem diameter varied from 1.349 to 0.370
cm and leaf area varied from 235 to 84 cm2. However, produced tubers number varied
from 9.3 to 2.8 and weight them from 740 to 155 grams and tuber weight from 75.2 to 24.6
grams.
The results also showed variations in the extent of tolerance between studied
treatments to salinity stress where 4T3P2 treatment was the most tolerant.
In this research we studied the corrosion rate changes of iron samples which are not
galvanized in the laborators ( laboratorsies of the faculty of science) and in nature (on the
beach of the high-institute sea- research in Lattakia)
The Inula ext
racts were choosen as a plant inhibitor to cover the iron samples and
protect it . because this plant is well known in the Coastal area, also it,s very cheap and
easy to find and has good anti oxidation properties.
The best conditions for (Inula-seawater) extract were : (PH=7 , time =24 hours ,
concent ration = 10%).
The studied iron samples were treated with the ( inula-seawater) extract in the same
previous conditions and we studied the corrosion rate changes for those samples and the
affectivity of the inhibitor for them.
The results were compared in each stage with other samples that were not treated .
the treatment and after it were as follows:
The velocity of the corrosion in the iron samples (before the treatment with the
extract) in 120 days:
- in the laboratory tanks was 0.78 mg/cm2 .day, but after the treatment was 0.23
mg/cm2.day
-in the drizzle area was 0.80 mg/cm2.day, but after the treatment was 0.47
mg/cm2.day
-in the waves area was 0.75 mg/cm2.day , but after the treatment was 0.41
mg/cm2.day
- in the depth area was 0.79 mg/cm2.day , but after the treatment was 0.21
mg/cm2.day.
